Title: How do I Make Asserts Behave the Way They Should on Linux?
Post by: jitspoe on May 22, 2008, 01:41:12 AM

So apparently Linux and/or gcc thinks asserts should terminate a program completely instead of just triggering a breakpoint and allowing me to step through it with a debugger.  How do I make them behave correctly?

I'm not sure about the "right" way to do this but here's a suggestion.

Code: [Select]

#include <signal.h>

#undef assert
#define assert(expression)  \
  ((void) ((expression) ? 0 : raise(SIGTRAP)))

Thanks - I'll look into that.
