I can think of three reasons for this:

  1. I had introduced a bug in egcs-1.0 that caused this. A workaround is
     to compile with -O2 and *no* -g.
  2. You have one of the pre-egcs-1.0.2 snapshots that still had the bug.
  3. You're using the compiler distribution with Gnu-Win32 b19. If that's
     the case, this is the least of your problems ;-)

If any of the above, upgrade to egcs-1.0.2; if none applies, then email me
and we'll figure out the problem. See

  http://www.xraylith.wisc.edu/~khan/software/gnu-win32/

for more info on how to upgrade to egcs-1.0.2.
