I had been suffering with some very nasty problems in my large C++
app, and our lead coder recently uncovered what they are. They
manifested most obviously with large STL code bases.

----- Begin forwarded message -----

dmalloc calls vfprintf on startup of your program, if you have a
logfile. fprintf saves errno. For multithreaded applications, errno is
a pointer to an area on the stack, which is not initialized by pthreads
at the very start of a program.

The innocuous line:
save_errno = errno;
causes a crash.

Sam will send you a patch soon.
