memory corruption

[GoogleCodeExporter]

Hello,

I'm trying to use RatProxy to test my Web application.

But sometimes, RatProxy break my requests and there is the following message :

*** glibc detected *** ./ratproxy: malloc(): memory corruption: 0x08ad7490 ***

I use RatProxy on a Debian 5 system.

If anybody can help me...

Thanks,

Thibaut

This is not enough information to diagnose the problem. When does the problem 
occur, exactly? Can you show me the stack trace / registers / current 
instruction output for the crash location (e.g. with gdb)?

Ok, the problem occurs when I click on a form "submit" button, and then the 
page doesn't load...
The complete message is the following :
