External exception as response to floating point errors

Hello,
on some new PCs (with faster processors, 800 MHz Pentium or 900 MHz AMD
Athlon) I have a problem with Delphi 5 which does not exist on other
(slower) PCs tested:

When a floating point error occurs, it does not raise the usual EMathError
exception but rather an "External exception", or a total system crash, or
first the external exception and the system crash soon afterwards.

I have seen similar reports in newsgroups like this one, but haven't seen
any solution. Is this issue (which should seriously affect many Delphi
developers) not yet resolved?

Look for the thread "Exception EMathError missing and fast cpus" in the
