--- Comment #1 from Marco Leise <marco.le...@gmx.de> --- Digger found this commit in 2.069: https://github.com/D-Programming-Language/dmd/commit/4f0a458f6072a281892f3d26fdd8aeb30d250c03 Since this can not be the commit that broke 2.068 I assume that it broke, got fixed unintentionally and then broke again. Something seems to be fuzzy about alloca() handling in the front-end. --
