In general, stack dumps are meaningless unless you have a debugging version
of the DLL with which you can match addresses and symbols.
The best way to track this down is to build your own version of the DLL and
then use either gdb or addr2line to figure out where the DLL is dying.
In gdb you can use 'l *0x61082720' to display the line. With addr2line,
the syntax is:
addr2line 0x61082720 -e /whereever/cygwin1.dll
