Please follow the instructions in doc/valgrind.txt.
By: Clod Patry (junky) 2008-03-21 07:32:51

I will do this tonight or tomorrow morning.
Can you explain me a little bit more about what may causing that sig 6 ?
In C++, i know a non-catched exception could result in a sig 6, what about here?
By: Tilghman Lesher (tilghman) 2008-03-21 08:09:44

In this case, it's memory corruption of the internal malloc structures.
By: Clod Patry (junky) 2008-03-29 00:04:06

I will try to reproduce this in a lab, cause i was getting that crash on a production system.
By: Tilghman Lesher (tilghman) 2008-04-21 17:54:38

Any feedback yet? We need valgrind output to proceed.
