Now the same php script runs without a seg fault!! I will give it a full test tomorrow when I can access via browser. Previous Comments: ------------------------------------------------------------------------ [2007-02-27 19:12:08] errol at issi dot co dot za Will do. I am at home and the embedded setup is at work. ------------------------------------------------------------------------ [2007-02-27 19:01:17] tony2001@php.net That's bad. The other request still applies, though. ------------------------------------------------------------------------ [2007-02-27 18:50:48] errol at issi dot co dot za It does not look like valgrind runs on ARM. See http://valgrind.org/info/platforms.html ------------------------------------------------------------------------ [2007-02-27 18:35:24] tony2001@php.net >Here is the backtrace Again, we would like to know where exactly it happens, not just the function name. Try to compile it with CFAGS="-O0 -g" and regenerate the backtrace. Btw, is there valgrind for Linux on ARM? It would help very much. ------------------------------------------------------------------------ [2007-02-27 16:23:26] errol at issi dot co dot za Here is the backtrace from the latest build I downloaded from snaps.
