Maybe the problem can be worked around by making the function(s) *weakly* pure?

Instead of removing the "pure", which is a breaking change, since it would
prevent pure functions from having an "onOutOfMemoryError", what about my
suggestion for weak purity?

void onOutOfMemoryError(void* dummy11461 = null) @trusted pure nothrow;
or just:
void onOutOfMemoryError(void* = null) @trusted pure nothrow;
instead of
void onOutOfMemoryError() @trusted /* pure dmd @@@BUG11461@@@ */ nothrow;
