Yes, that is what struck me too. However, OTL is only a header file
and so is always built along with the application.

ospace is different and interesting. It is built with  2.96-98. The
gcc version that I am using to build the application is  2.96-129.7.2.
I had thought that since it is the same version (2.96), the patch
update differences would not be a problem. Do you think that even
those might make a difference?

Though I still don't know why it is crashing, your comments have
helped a lot ...

And this is also where I am facing problems. I too thought that
building with 3.x.x would be better. However, the application is
actually using 7-8 different libraries. All of them built using gcc
2.96 (with different patch updates) ...

Converting them all to 3.x.x is ... problematic.

Now I am really stuck. :-(

I know only a little about disassembling and assembler. However, any
pointers (if possible) in this direction (such as what to look out for
etc.) would be very helpful. (Sorry about the vagueness of this
question :-))
