Everything was built from sources using gcc 4.8.0 on a SPARC/Solaris 10 platform. The crash can be triggered by invoking php at the command line with the test script below. The crash occurs shortly after the SSL certificates have been read. Here is an excerpt from truss (tool similar to strace): open64("/usr/local/gcc48/openssl/cert.pem", O_RDONLY) = 4 fstat64(4, 0xFFBFD770) = 0 brk(0x00DB1C40) = 0 brk(0x00DC1C40) = 0 fstat64(4, 0xFFBFD618) = 0 ioctl(4, TCGETA, 0xFFBFD6FC) Err#25 ENOTTY read(4, " # #\n # # B u n d l e".., 131072) = 131072 brk(0x00DC1C40) = 0 # ... many more brk system calls read(4, 0x00DA070C, 131072) = 0 llseek(4, 0, SEEK_CUR) = 250615 close(4) = 0 Incurred fault #6, FLTBOUNDS %pc = 0x004CA154 siginfo: SIGSEGV SEGV_ACCERR addr=0xFEF57A5C Received signal #11, SIGSEGV [default] siginfo: SIGSEGV SEGV_ACCERR addr=0xFEF57A5C Test script: --------------- <?php $ch = curl_init("https://de.wikipedia.org/wiki/Ulm"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_BINARYTRANSFER, true); if (!$content = curl_exec($ch)) { echo "FAILED:"; trigger_error(curl_error($ch)); } else { echo "OK:"; echo $content; } curl_close($ch); ?> Actual result: -------------- clonard$ gdb /usr/local/php-5.6.24/bin/php GNU gdb (GDB) 7.5.1 Copyright (C) 2012 Free Software Foundation, Inc.
