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
