...e allocating stack manually, but I could be wrong. What triple are you using with LLVM to generate code? There isn't much else information here, but you can try to zero in on the problem by checking the stack alignment manually with a helper like: void CheckAlignment() { assert((((uintptr_t)_AddressOfReturnAddress() + 8) & 15) == 0); } Run this near where LLVM calls back into C code. If it fails, disassemble the calling LLVM function and look at that to see if there's something wrong with the prologue. Sending that along with any followups would be helpful.

Hi, I wrote sometime ago about this issue (see links below). http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/084089.html http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-April/084193.html At the time I thought the problem was due to a bug in my code, and that I had fixed it. But sadly it seems that the issue is still present - it just got hidden by whatever change I made. The error only
