Hi,

attached example, executed on Linux i686 (!), crashes likely due to the caller
and callee disagreeing on the stack layout / call setup / SRet passing.
Commenting JIT.cpp 406-451 (the shortcuts for the common cases) makes it work.

Should there be a "&& ! F->hasStructRetAttr()" in that shortcut condition, line
406?

Axel.
