We will need the preprocessed source code and the command-line.  The
easiest way to do that is to compile with "-v -save-temps".  Send both
the ".i" file generate and the output shown when compiling in that mode.

Obviously, the compiler shouldn't crash, but it's quite likely that the
cause are the asm register tricks being played in that function.
Playing with the stack pointer behind GCC's back is likely to result in
bad things happening.  Such functions really need to be coded in
assembly, or at least with blocks of inline assembly.
