Hi folks !

I've written a C++ programm, (compiled about 150k), which uses
much of floating point calculations ('+', '-', '*', '/', '<' '>',...)
I use both Borland C++ compilers (Version 2 and 3), with the same
result:
When I run the program, everythink is just fine, but when all
is done (at the end of "main()"), it just "hang" the system
(I have a 386 board, without 387) with the following message:

   floating point error: stack fault
   memory allocation error, unable to load COMMAND.COM
   system stoped

So I tried the program on a 486, under nearly the same contitions
-> NO PROBLEM, now I believe, there must be a problem, under some
conditions, with the Borland FPU-emulation-library. I ordered a
387 for my home system today, but thats not realy a solution ...

Any idea ?

Heiko
