php - Why is APCu segfaulting inside a Docker container? -


i'm trying run php 5.5 (with fpm) apcu inside docker container. i'm using boot2docker on osx.

when try run php-fpm -i, segfaults.

running in gdb, following backtrace:

(gdb) run -i starting program: /usr/local/sbin/php-fpm -i [thread debugging using libthread_db enabled] using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".  program received signal sigsegv, segmentation fault. 0x00007ffff542474c in __pthread_rwlock_init (rwlock=rwlock@entry=0xffffffffffffffff, attr=attr@entry=0x7ffff1bda988 <apc_lock_attr>) @ pthread_rwlock_init.c:40 40  pthread_rwlock_init.c: no such file or directory.

i thought might general problem phtreads in docker container, haven't been able find reports of kind of problem.

some questions:

  1. is known issue (and, so, trying fix through configuration fruitless)?
  2. what significance of 40 pthread_rwlock_init.c: no such file or directory.?

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...
