The original, unreduced, testcase from pr42521 started crashing again, with the
same error message. Only little modification to the reduced testcase is needed
to reproduce it.
Command line:
gcc -O3 -fgraphite-identity -c testcase.c
Tested revisions (x86_64):
r155945 - crash (x86)
r155938 - crash
r155902 - crash
- r155881 - pr42732 fix (can be related)
r155844 - OK (x86)
r155833 - OK
- r155728 - pr42521 fix
r155363 - crash
Output:
$ /mnt/svn/gcc-trunk/binary-155945-x86-lto/bin/gcc -O3 -fgraphite-identity -c
