I want a workabout for this bug: http://d.puremagic.com/issues/show_bug.cgi?id=3717
Basically, a C function that returns a structure and is compiled with a non-DMC compiler thrashes the stack when called from D. Here's the assembly code for a function that does it (sorry for the AT&T assembler syntax): <_al_map_rgba>: push %ebp mov %esp,%ebp mov 0x8(%ebp),%eax movzbl 0xc(%ebp),%edx mov 0x66d24020(,%edx,4),%edx mov %edx,(%eax) movzbl 0x10(%ebp),%edx mov 0x66d24020(,%edx,4),%edx mov %edx,0x4(%eax) movzbl 0x14(%ebp),%edx mov 0x66d24020(,%edx,4),%edx mov %edx,0x8(%eax) movzbl 0x18(%ebp),%edx mov 0x66d24020(,%edx,4),%edx mov %edx,0xc(%eax) leave ret $0x4 lea 0x0(%esi),%esi It's signature is this: ALLEGRO_COLOR al_map_rgba(ubyte r, ubyte g, ubyte b, ubyte a); Where ALLEGRO_COLOR is a quad of bytes. What I want is some sort of inline assembly preamble (and/or postamble, as it were) that will make it possible for me to call that function correctly. The suggestion made by Walter in the bug report is unacceptable for my purposes. What I have tried is this: ALLEGRO_COLOR get() { auto c = al_map_rgba(255,255,255,255); asm { sub ESP, 4; } return c; } But it did not work. Any help appreciated. -SiegeLord
