I wonder if this is a familiar bug to someone.

The problem is:
Sometimes my program causes a segmentation fault. If I drive it with
CVP I can find out (from calls sequence) that the error was caused by
malloc. To be exact, malloc calls an internal(?) function named
_searchseg() that fails. Any ideas what this function might be?

I use MSC 6.00 in OS/2 1.3 environment.

I write programs for Lotus Notes using Lotus Notes API libraries. (But
I think it is irrelevant to the promlem). 
The memory model used is Large.

My program uses a lot of dynamic memory allocation, but I am quite
sure that there is no bugs in my code. I have spent two days checking
out the memory allocation of this program.
