The "failed reading symbols" warning are valid; those DLLs don't
have symbols.  The other messages are just gdb telling you where
DLL's ended up being loaded in memory.

Well, in lieu of a concrete example, I'll won't hazard a concrete guess
about what you mean.  One thing it might be any call from a DLL.

In general, the thing to do when you don't have any trace at all is to
do a divide and conquer search: set a breakpoint somewhere in your
code you think is reached.  If successful (the breakpoint is hit), set
the code farther into your code.  If a crash occurs, make a more
conservative guess.  Rinse and repeat.
