I get the same error, and merging revision 197165 from trunk into my working-directory for gcc-4_8-branch revision 198253 did not fix the error on my system. This error occured during one of the stages while building gcc, revision 198065, checked out from svn://gcc.gnu.org/svn/gcc/branches/gcc-4_8-branch for MinGW32, Windows 7 Pro 64-bit SP1. The error also occurs with revisions 198027 and 198253 -- that is, the error has been occuring with revisions for at least these past 7 days. The error persists after I merged revision 197165 from trunk into my working-directory for gcc-4_8-branch revision 198253. That's expected as the issue I fixed on trunk was not present on the 4.8 branch. Which is why I didn't close this bug. But as I cannot reproduce it I rely on others for investigation. Can you please provide a backtrace from the crash?

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56716 --- Comment #6 from Greg gccbugzi...@tru-traffic.com 2013-04-25 22:32:13 UTC --- 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?
