label
Product: dragonegg

Compile this program with LLVM gcc and -O1 to exhibit the bug
Taking the address of a label, as in &&foo where foo is a label, does not
generate correct code. This is used extensively in the C code generated by the
Gambit Scheme compiler for implementing tail calls in C with computed gotos,
i.e. goto *pc.
See attachment for details.
