I compiled ruby 1.9 from trunk on cygwin.  Initially, the only option I gave to configure was –program-suffix=19.
I got a crash when I ran the interpreter and fed it one line of code (‘puts “yo”’).  I since tried to recompile
without ext/tk and with --disable-pthreads, but I still get crashes in the same place.  Here’s the backtrace:

Follow up:
I had a typo in my configure command: it should have been
--disable-pthread.  Now when I try that, the build fails:

make: *** No rule to make target `thread_.h', needed by
`error.o'.  Stop.

Also, as the backtrace shows, I haven't really disabled
tktcllib... I commented out the line 'tk' from ext/Setup,
what else do I need to do?  I suspect the crash is caused by
the fact that my tcl is not compiled with threads...
