I did that info threads && thread N dance but that didn't work.

Ok, I'm just confused what is the layout the the lastest/* tree, but I
think I understand it now. I'm was just consfused that there wasn't a
configure in the top dir in lastest/gdb/gdb-20000415.tar.gz tar-ball.

I mean the mail that DJ send to the mailing list.
I have another problem too. I have a program that crashes under cygwin
(works for many other) and I suspenct that the error is in cygwin1.dll
since that is what the debugger in VC claims the error is. Its refences 0x4
an get a "Application Error". gdb is just confused and can't do the
intresting stacktrace (see below). How do I make sure the error is in my
program and not cygwin1.dll ?
I can give you a tarboll with binaries that cause the error.
Program received signal SIGSEGV, Segmentation fault.
[Switching to thread 608.0x460]
