Bug #71492 [NEW]: Segmentation faults all the time
From: Birman at Cerberox dot com
Operating system: CentOS 7.1.1503
PHP version: 7.0.2
Package: *Web Server problem
Bug Type: Bug
Bug description:Segmentation faults all the time
Description:
------------
Installed php70w package on CentOS. Everything installed fine and Apache
2.4.6 picked it up with no problems and all the web services seem to
work. However, when I take a look at the logs, after around 5 minutes it
gets spammed with Segmentation faults:
[Mon Feb 01 17:09:47.812393 2016] [core:notice] [pid 12430] AH00052:
child pid 12457 exit signal Segmentation fault (11)
[Mon Feb 01 17:13:37.999297 2016] [core:notice] [pid 12430] AH00052:
child pid 12605 exit signal Segmentation fault (11)
[Mon Feb 01 17:14:08.027445 2016] [core:notice] [pid 12430] AH00052:
child pid 12601 exit signal Segmentation fault (11)
Funny thing is that when using the website, everything seems to be fine,
so whatever it is, it doesn't affect the usage (or it's able to recover
from it quickly).
Also ran the gdb for you, this is what I got:
Try 1:
Program received signal SIGSEGV, Segmentation fault.
sljit_malloc_exec (size=1968) at
/usr/src/debug/php-7.0.2/ext/pcre/pcrelib/sljit/sljitExecAllocator.c:196
196 header->prev_size = chunk_size;
(gdb) step
Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
Try 2:
Program received signal SIGSEGV, Segmentation fault.
0x00007fffea3c1e48 in sljit_malloc_exec (size=2032) at
/usr/src/debug/php-7.0.2/ext/pcre/pcrelib/sljit/sljitExecAllocator.c:189
189 if (free_block->size >= size) {
(gdb) step
Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
