pragma(crt_constructor) extern(C) void mir_cpuid_crt_init() { } dmd -lib -oflibmir-cpuid.a source.d Segmentation fault: 11

Same here, we also hit this: -------- main.d ---------- extern(C) pragma(crt_destructor) void deactivateDRuntime() { } -------------------------- dmd -lib main.d

Can be workarounded by using LDC. Can be workarounded by compiling in one bunch with --combined of course.
