Hi Starting with a commit:
commit 45bf20ad3f799bf219958c3ba705898440c74e4a Author: Ilya Tumaykin <[email protected]> Date: Thu Aug 30 11:36:34 2012 +0400 wMNAF-based multiplication php started to segfault here. To reproduce here I'm using php cli program + module gmp and curl. Uninstalling php gmp module and the problem is gone. My curl uses gnutls. The fact that I need gmp php module to reproduce makes me wonder if there is some global state (maybe in gmp) that's overwritten by gnutls? Any ideas/hints on what can be going on here? Thanks, ps. to reproduce, php + curl php module + gmp php module. Run php cli and press ctrl+d. Program received signal SIGSEGV, Segmentation fault. 0x00007fffea23ef20 in ??
