RE: [GD-Windows] Finding routine that's crashing

[Andrew G. <ag...@cl...>]

Err yeah. It was late that night ok! :)

I think the two extra FF's are a typo as that buffer is just used to =
store
the current working directory, why it's not on the stack is probably a
result of me not tidying things up properly.

I had all sorts of nightmares trying to get that stack trace stuff =
working
reliably on versions of Win9x so as a result that whole file which =
deals
with retrieving the callstack and symbol names ended up being quite =
messy as
I tried various things, and at the end I just ran over the file quickly =
to
tidy things up.

Thanks, I might clean it up and bung it on flipcode or something. I =
still
use that DLL as a drop for projects as it's very handy, but haven't =
looked
at the source since last year when I wrote it.
