If anyone knows where my avifile is seg faulting and why, please let me
know. I get segmentation faults when running avifile with and without
arguments. Anyway, here's a list of some relevant packages on my box:
qt-2.3.0-3
qt-devel-2.3.0-3
qt-designer-2.3.0-3
SDL-1.2.2-1
SDL-devel-1.2.2-1
I have tried a Mandrake precompiled binary (avifile-0.53.5-1mdk.i586.rpm)
wich produces a seg fault at the same point I get it when I try to compile
the package. By the way, since I am running Redhat 7.1, I have tried
compiling with gcc version 2.96-81, 3.01, and in the case of the back trace
I will provide, version 2.95.3. I thought that this last compiler should
clear up the problems for sure, since it has always been so stable for me.
I have been trying to use that latest package, avifile-0.6.0-20010817. I am
running Redhat's excessively patched 2.4 kernel, although I would think that
shouldn't matter. I am running X version 4.0.3
I think that this gdb session should tell all:

Now when I look at main.cpp, I see that the program is allocating new space
on the heap for a MyWidget. I am not sure why this allocation is failing.
If anyone has seen a similar problem, could they please let me know?
If I can provide any more information, tell me, and I'll send it.
Thanks,
Richard Davis
