I think it must be b18 (or b18+Mingw32) related as I had the same program
built with b17 running for several weeks of intensive testing. The only change I
have made in going to b18+ming is to use time() instead of gettimeofday().
The problem is intermittent, the same run will sometimes crash, sometimes not. My
client gets the same thing sometimes. I think the problem is corruption of the
heap, but I can't think how to detect when it actually happens - my crash happens
at the end of a long run which does thousands (millions?) of small allocations
and deallocations of memory.
