This is a FAQ.  Section 13.2 of the DJGPP FAQ list explains that there
is a bug in a library function used by programs compiled with -pg
which causes this (and can even crash profiled programs in some
configurations).  Get a patched version of the library from Tom
Demmer's site and relink your program against it.
