No.  Please tell more about what the program does.  If you run the program
from Bash, try running it from COMMAND.COM and see if this helps.

Also, when it gets stuck and you interrupt it with Ctrl-BREAK, it should
print a DJGPP-standard traceback.  Please tell where does this traceback
point.

Finally, please tell what happens if, after the crazy behavior commences, you
run a small program that calls _clear87 and _fpureset, and then exits.
