Thank you dmitry. Previous Comments: ------------------------------------------------------------------------ [2011-11-08 11:25:30] dmitry@php.net try to make full PHP rebuild (make clean; make install) In case it doesn't fix the problem, I need a reproduce case anyway (or at least an ability to analyse crash dump on a remote system). ------------------------------------------------------------------------ [2011-11-08 11:02:14] patrickallaert@php.net Description: ------------ Segfault that happens since revision 318671 (Fixing #60139). Test script: --------------- For now, I can only repeat this with phpunit if putting 4-5 tests together, not a single test script is able to reproduce it. I can take some time if it is really required. Expected result: ---------------- No segfault :) Actual result: -------------- Program received signal SIGSEGV, Segmentation fault. 0x00000000012433a0 in ?? () (gdb) bt #0 0x00000000012433a0 in ??
