c++ - scppn.exe process crash

Just had another nasty - a crash rather than an ICE - which had an
interesting cause. On earlier compilers, it compiled fine, but 8.31+ it was
toast.

It was caused by an iterator class - a helper for a TREEVIEW-wrapping
sequence class - that had previously relied on operator ==() and operator
!=() being free functions. In making the code work for other compilers
(notably Intel, GCC & Metrowerks) they required that the operators be
changed to public const member functions. However, I forgot to remove the
free functions. All other compilers (and previous versions of DMC++) happily
ignored the free-functions, but 8.31+ was very cross.

Don't know if this is helpful, but thought I'd let you know. I would imagine
you'd rather the compiler report an error (although I'm pretty sure it's not
an error - it would seem like a pretty stern situation - albeit that it is a
useless thing to have) than crash.

I need a test case that causes the crash so I can fix it. Thanks, -Walter
