RE: [mpatrol] Segmentation fault

Hi,
 
You can't selectively choose which libraries in a program to run with mpatrol - it has to be the whole program or nothing (unless you link the shared library in question with libc.a, but then you'll open a whole can of worms if you pass and receive pointers to allocated memory).
 
That said, the crash looks to be occuring when mpatrol is working out the stack trace.  It looks to be an Intel i686 processor you're running it on.  What stack trace mechanism is mpatrol using - the default or one of the MP_*STACK_SUPPORT macros in config.h?
 
Graeme.

Also, ran into to this issue. When the application is started it
dies, so tossed it into gdb and get the following stack trace..

It is trying to trace into an intel library MLK (math kernel library)
is there so how I can skip over this library? Or some way not to
trace this one?

If you haven't changed the mpatrol source code then it'll be using the default so that answers my question ;-) There's a signal-handler in the mpatrol stack...
