I have a project that I've compiled under RH6.2 with gcc/g++ 2.95.2.
The strace program has the following output:
execve("../../PinnacleStatic/bin/linux/pinnacle",
["../../PinnacleStatic/bin/linux/pinnacle"], [/* 59 vars */]) = 0
brk(0) = 0x873d724

Starting program:

Program received signal SIGSEGV, Segmentation fault.
0x400037b6 in ?? ()
The main function is the first function in the program. Obviously it isn't
even getting that far before it dies.
Any pointers as to what I need to do to try and figure out where the program
is croaking will be appreciated. If there is a better mail list to join in
which to get help on this, please let me know and I'll move the question to
that mail list.
Thanks.
