> Can you please provide a backtrace from the crash?



I'll be happy to provide a backtrace from the crash.  It will take a day or so,

as I'm such a novice that I don't yet know how to create a backtrace.



In the meantime, here's a new development: The build that crashed was launched

using



make BOOT_CFLAGS='-O' bootstrap



Thinking that I'd need to remove the BOOT_CFLAGS='-O' in order to create a

backtrace, I rebuilt using simply



make bootstrap



Only this time, the bootstrap built to successful completion -- no crash.



This used revision 198253 with no changes (that is, I'd first reverted from my

working-directory the revision 197165 merged from trunk).



Any tips for a novice on how to create a backtrace from the crashed build?
