------- Comment #2 from jakub at gcc dot gnu dot org 2010-02-10 09:11 -------
This is actually a regression from 4.3, caused most probably by
http://gcc.gnu.org/viewcvs?view=revision&revision=139159
For VLAs GCC errors out if a goto jumps into a scope with a VLA, for
-fstack-check it obviously can't error out, but probably needs to avoid
emitting the stack checks in that case, or conditionalize them.
