I am a bit unclear what version of gcc was used for the "fast" precompiled
octave. Was it really gcc-3.2.3 or gcc-3.2-3 (the third cygwin update of gcc-
3.2.0)?
What does gcc -v say for the gcc that built the "fast" octave.
The cygwin gcc-3.2 distro's (dated about August 2002) had a local patch that
enabled Dwarf2 exceptions. This worked fine except when functions throwing
exceptions were used as callbacks by win32api functions. So the experimented
was terminated and the EH model was reverted to sjlj in later binary distro's
of gcc.
If this is really a difference between sjlj and Dwarf2, I think it is time to
revisit Dwarf2 support on windows targets.
