well, it turns out Dave's suggestion doesn't work anymore on latest cygwin 
(tested this only with C++ programs):
GNU gdb 6.3.50_2004-12-28-cvs (cygwin-special)
gcc version 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125)

In fact, it will now break before entering main(), but not when the assert is 
called.

Using "break __assert" says
(gdb) break __assert
Breakpoint 1 at 0x4ac3e6: file /usr/lib/gcc/i686-pc-
cygwin/3.4.4/include/c++/iostream, line 77.
(gdb) r 
Starting program: /home/kris/MyDocuments/mytest.exe

Breakpoint 1, __static_initialization_and_destruction_0 (__initialize_p=1, 
    __priority=65535)
    at /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/iostream:77
(gdb) c
assertion "overlap>-epsilon" failed: 
file "./include/stir/numerics/overlap_interpolate.inl", line 108

Program exited normally.

Any other suggestions?

Thanks

Kris
