--- Comment #3 from Christoph Haag <haagch at frickel.club> ---
I think it's a similar alignment bug like the one clang has produced some time
ago for me when compiling llvm: https://llvm.org/bugs/show_bug.cgi?id=21097#c4

0x78f6f76e in LLVMAddTargetDependentFunctionAttr () from
/usr/lib32/libLLVM-3.8svn.so
Wine-gdb> disassemble

Googling "llvm movaps alignment" brings up several related bugs.
