Application crash on release build

[LunaTheFoxgirl]

An application I'm writing that is using SDLang-D crashes on release builds even though it works in debug builds.

Backtrace from release-debug

[Abscissa]

Crashes on debug-only or release-only almost always indicate a bug in the compiler. But regardless of where the bug is, a reduced test case (including how the compiler is invoked) will be needed to track this down further.

Will do asap
