What is the good tool to debug for segmentation error

[mxu1]

Hi, 

I tried several utils to debug one C program ( hoc from Software Tools ) which 
gives me segmentation error but got no clue from them.

The most hopeful one gccchecker failed to compile it in the linking stage:
reporting undefined reference to `chkr.__sigsetjmp'. Anyone knows how to deal 
with it?

And any better tool than gccchecker?

My system is potato.


Thanks.
