--- Comment #3 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
OK.
AFAIK Cygwin-32 does not support the unwind info at all, right?.
Cygwin-64 does support Windows-SEH style unwind info.
libjava uses a kind of hack to get the stack trace:
see libjava/sysdep/i386/backtrace.h
I've seen java exceptions with call stack using above patch.
