build log
I can't make it fail here. Go into /var/tmp/portage/media-libs/mlt-0.7.8/work/mlt-0.7.8/src/modules/lumas and run the failing command with -save-temps added. Attach the .i file it produces. Created attachment 313791 [details]
luma.i
So, with O3 it fails even with 4.7.0 (tested right now)
Despite the fact that upstream reports mentions it happens even with 4.4 I was unable to reproduce it with 4.5. With 4.6 fails as described by original reporter Created attachment 313795 [details]
reduced testcase
Created attachment 314075 [details]
new_luma.i
so I pasted your test case into place of old code and here is output.
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=188170 4.7.1 should be out shortly so we won't bother with a new patchset. 4.7.1 is in the tree now |
