I'm still using SDL 1.2.4 here, so I'm not sure whether this is of any
help. It crashes just as you say: here's all the output (just in case):

And here is the backtrace:

The same as yours, but mine also displays the line numbers of the SDL
code. Not that this would help much, as the code in question is quite
tricky :(.

OTOH, could it be a problem with our own code? Wouldn't be the first
time ...


On the matter of wstring and g++ 2.95: to my surprise, wstring is
defined in /usr/include/g++/string, however, that line is commented!
I didn't want to mess with the system headers, so I typedef'd it in our
code, and it works fine.
