File a bug against gdb, it should work (it works under Mac OS X and

First I need to be sure that this is a gdb bug. Maybe fpc doing a
bit different handling on osx and windows?
That is irrelevant:
a) it works without gdb
b) it doesn't work in gdb if you tell gdb to ignore all signal handlers
Just make sure you include a compiled program so that the gdb
maintainers don't have to install FPC to test.
Jonas, can you write a small similar C++ test?
No, because
a) the C++ exception handling system does *not* automatically catch OS
or hardware exceptions, it only catches exceptions raised by C++ code
(so you need to write a hardware-exception-to-C++-exception conversion
framework, similar to the code in our RTL for converting hardware/OS
exceptions into Pascal exceptions)
b) I don't know how to catch signals under Windows (and am not
interested at this time in learning low level Windows programming)
c) my C++ knowledge/experience is extremely limited
A simple C program that triggers an FPU exception without installing
any handlers, is of course easy (just make sure to compile it without
optimizations, so the dead code is not removed):
int main()
{
double a, b;
a=1.0;
b=0.0;
a=a/b;
return 0;
}
