The information given by that backtrace is completely useless since
XWin as well as the Cygwin DLL don't contain debugging symbols. The
addresses have no meaning w/o that info. The only interesting fact
in the backtrace is:
#0 0x77e8c40c in _libkernel32_a_iname ()
#1 0x00000001 in ?? ()
At this point, a function at address 1 (obviously a wrong pointer) is called
#2 0x6103f35f in _libkernel32_a_iname ()
from *any* function in the Cygwin DLL
#3 0x6103f38b in _libkernel32_a_iname ()
#4 0x6107b7df in _libkernel32_a_iname ()
#5 0x6107baba in _libkernel32_a_iname ()
#6 0x0043b838 in _size_of_stack_reserve__ ()
which has been called from *any* function in XWin.
