Bug #70079 [NEW]: Segmentation fault after more than 100 SoapClient calls

From: dmifedorenko at gmail dot com Operating system: Linux vm 3.13.0-37-generic #64-U PHP version: 7.0Git-2015-07-15 (Git) Package: Unknown/Other Function Bug Type: Bug Bug description:Segmentation fault after more than 100 SoapClient calls Description: ------------ Hello. Almost several weeks I see the same strange bug in last PHP7 master. I can reproduce it on several different PCs in our office (apache2 or nginx), but cant give you fixture to reproduce it. Description of problem. We have 150 calls of SoapClient to old Jira endpoint (method getIssueByKey) inside foreach. After all data received PHP7 trying render html and falls with seg fault inside outerLayout.inc.php template file. The only content of file is "<?" - two simbols. If I remove include of this file fatal will happen on next template. Looks like inlude broken? In apache2 log I see entry: [Wed Jul 15 15:36:45.538571 2015] [core:notice] [pid 9031] AH00051: child pid 9036 exit signal Segmentation fault (11), possible coredump in /tmp If reduce limit on SoapClient to 80 calles all works perfect, but after about 98 calls include will be broken. Check out core file's backtrace please: --- #0 0x00007f688851ed7f in zend_mm_alloc_small (heap=0x7f687e400040, size=56, bin_num=6, __zend_filename=0x7f6888ab3458
