This is no indication whatsoever.  I have code which runs perfectly
on Cygwin but crashes on my 64 bit Linux installation.  The cause is
simply a missing header file.

The call stack shows that it happens in your code.  It shows nothing
else.  You will have to build your application with -g and debug it
with gdb the usual way.
