Thats what I looked at. I placed a pause just before where I was getting
the error, and found that it was nowhere near the largest memory
allocations on my beast (Which is something like 8Mb for one program). So
I tried using electric fence...

I have tried changing many of the switches, and even tried without
switches (Optimization may have caused a problem I thought, but it was
not).

I isolated the memory alocations, and the error did not occure. So it had
to be the memory allocations.

As I have said, I have found the solution (thanks for your help guys). I
have not exactly solved the problem yet, as the line is just commented
out. There were two problems:

1) I was using sizeof instead of strlen for a string - very stupid
mistake.

2) This is the one I can not fix (Electric fence found this one at a
higher level than where the code was crashing): I am using strcpy to copy
a string. The destination string has been allocated the right ammount of
memory, but when it copies, I get the segmentation fault. I do have
another way round the problem if I can not figure out why it is crashing.


Thanks for any help. And now I must go and thank whoever made electric
fence (I must also read through the stuff on its usage and copyright -
whoops)...
