Corrupt when using Google Play Services Face Detection in Picasso Transformation. (Fatal Signal) -


i'm writing face crop transformation of picasso.
make face in image shown when picasso cropping image.
implement picasso transformation , using face detection in function public bitmap transform(bitmap source).

import com.squareup.picasso.transformation; .... public class facecrop implements transformation {     ...     @override public bitmap transform(bitmap source) {         facedetector mfacedetector = new facedetector.builder(mcontext).settrackingenabled(false).build();         if (!mfacedetector.isoperational()) {             return source;         }         frame frame = new frame.builder().setbitmap(source).build();         sparsearray<face> faces = mfacedetector.detect(frame); // crash here         ...         rectf rect = null;         (int = 0; < faces.size(); i++) {             face face = faces.valueat(i);             float x = face.getposition().x;             float y = face.getposition().y;             rectf facerect = new rectf(x, y, x + face.getwidth(), y + face.getheight());             if (rect == null) {                 rect = facerect;                 continue;             }             rect.union(facerect);         }         mfacedetector.release();         ...          bitmap bitmap = bitmap.createbitmap(mwidth, mheight, source.getconfig());         canvas canvas = new canvas(bitmap);         canvas.drawbitmap(source, null, targetrect, null);         source.recycle();         return bitmap;     } }

for images, works perfectly. nothing wrong.
specific images, works fine, crashes @ sparsearray<face> faces = mfacedetector.detect(frame);. (it's not crash 1 image.)
tried use try , catch block catch error, still crash anyway. can't skip it.
, error messages different every time, similar.
"fatal signal x (sigabrt)...".
here 4 examples :
1.
invalid address or address of corrupt block 0xba362ba0 passed dlfree
fatal signal 11 (sigsegv), code 1, fault addr 0xdeadbaad in tid 10651 (picasso-/extern)
2.
fatal signal 11 (sigsegv), code 2, fault addr 0x93948000 in tid 16443 (picasso-/extern)
3.
fatal signal 11 (sigsegv), code 1, fault addr 0x605f5e6a in tid 17951 (gcdaemon)
4.
heap corruption detected tmalloc_large
fatal signal 6 (sigsegv), code -6 in tid 19020 (picasso-/extern)


sure parameter frame of function detect not null.
checked images cause crash, can't see wrong them.
looks normal, , not large files (smaller 1m).
faces, not.
, can decoded picasso picasso's center crop.

can give me suggestion?
thank much!!

there known issue small images, , fixed in future release. fortunately, there patch available on github now:

https://github.com/googlesamples/android-vision/issues/26

if still getting issue patch, please print out of image sizes , post here debug.

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
