I could include the OpenSolaris header, which is licensed under CDDL,
but I've just been able to construct a minimal testcase:
$ cat include.c
#include <stdlib.h>
$ cat stdlib.h
#pragma redefine_extname mkstemp64 mkstemp
$ ./cc1 -E -traditional-cpp ./include.c -o include.i -I . -m64
In file included from ./include.c:2:0:
./stdlib.h:1:0: internal compiler error: Abort
This should make it easier to find what's going on. Unlike the original
test case from the GCC testsuite, this one fails even without -m64.
