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.

luma.i

So, with O3 it fails even with 4.7.0 (tested right now)

[Comment 4 Kacper Kowalik (Xarthisius) (RETIRED) 2012-06-01 08:30:45 UTC]

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

new_luma.i

so I pasted your test case into place of old code and here is output.

4.7.1 should be out shortly so we won't bother with a new patchset.

[Comment 8 SpanKY 2012-07-18 11:56:24 UTC]

4.7.1 is in the tree now
