#35575 [Opn->Bgs]: gettext call segfaults with memory allocation error

ID: 35575 Updated by: tony2001@php.net Reported By: tokul at users dot sourceforge dot net -Status: Open +Status: Bogus Bug Type: Gettext related Operating System: OpenBSD 3.8 PHP Version: 5CVS-2005-12-06 (snap) New Comment: If it happens because OpenBSD developers rewrote malloc()'s code - report that problem to them. Previous Comments: ------------------------------------------------------------------------ [2005-12-07 09:34:06] tokul at users dot sourceforge dot net It is specific to OpenBSD. They rewrote malloc code in v.3.8. You need ru/LC_MESSAGES/test.mo file in order to reproduce it. I think any compiled gettext translation file can be used for test.mo. I can reproduce problem with standard gettext library distributed with OpenBSD. gettext v.0.10.40. If php is compiled against GNU gettext 0.14.3, script works as expected without segfaults.
