I got:
mayalias-2.c:2: internal compiler error: in splice_child_die, at
dwarf2out.c:5552
with a modified compiler, but I see that it fails on powerpc64-linux
<http://gcc.gnu.org/ml/gcc-testresults/2006-08/msg01176.html> and arm-none-eabi
<http://gcc.gnu.org/ml/gcc-testresults/2006-08/msg01185.html>, so it's probably
pretty common.
The problem is that the front-end is calling the DWARF output code with two
shallow copies of the same structure, 'S'. The DWARF code detects that two
different structures have the same members and aborts.
