Subject: [Bug c++/59131] New: Compiler segfaults while generating code to save local variables in transactional section
Date: Thu, 14 Nov 2013 14:15:00 -0000	[thread overview]
Message-ID: <bug-59131-4@http.gcc.gnu.org/bugzilla/> (raw)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59131

            Bug ID: 59131
           Summary: Compiler segfaults while generating code to save local
                    variables in transactional section
           Product: gcc
           Version: 4.7.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: machens at tuhh dot de

I've analyzed code generated to save and restore local variables in
transactional sections and wrote some tests with very much local variables
(exceeding the capacity of the CPU registers). At some point the compiler
segfaulted. I've attached the code to allow you to further investigate it.



/usr/bin/g++-4.7 -fgnu-tm -Wall -g -O3 -o gnutm-test compiler-segfaults.c -litm
