...d parse/verify OK. Attached is the assembly. It is the smallest example generated that causes the segfault. If this EE uses a recursive function (??), it seems an inherent limitation in how big llvm functions can be.

Hi Simon, You're probably right. LLVM's instruction selector is recursive so it can run out of stack space. Select_store used to have enormous stack frame (thanks to some gcc issues), we had to do all kinds of tricks to get it under control. I just took a look at it, it's around 0.7k. It used to be around 20k on x86 Mac OS X. It's also possible that it has gotten into a real infinite loop. I'll...
