This problem was found when building mozilla. Creating a struct which
contains a va_list element (which is actually a __builtin_va_list) causes
the C++ compiler to seg fault.
The problems is not seen when using the C compiler or compiling for sh3
(only sh4). It is preset in gcc 3.0.3, 3.2.1, 3.3.2 and 3.4 snapshot 20030222.
I suspect it was not present in gcc 2.95, but cannot confirm this.
To reproduce:
% /var/tmp/gcc-3.4-20031126/objdir/gcc/xgcc
-B/var/tmp/gcc-3.4-20031126/objdir/gcc/ -O0 nsTextFormatter.ii -m4 -c
nsTextFormatter.ii:4: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
% cat nsTextFormatter.ii
typedef __builtin_va_list __gnuc_va_list;
typedef __gnuc_va_list va_list;
struct NumArgState{
va_list ap;
};

I can't reproduce this with a more recent snapshot on x86 linux.
Can you
a) use with a recent CVS snapshot?
b) say something whether this is sh specific, i.e. does it not
crash on x86 for you?

I cannot reproduce it on powerpc-apple-darwin so it is a target bug, will look into to see if
I can reproduce it on a cross to sh later today.

I know next to nothing about the guts of gcc, but sh_build_va_list
(gcc/config/sh/sh.c) calls make_node() whereas the other archs call
*lang_hooks.types.make_type(). Could this be relevant?

Yes that would be a problem, so this is definitely a target bug.
The fix to most of the other targets were changed by:
<http://gcc.gnu.org/ml/gcc-patches/2002-03/msg01864.html>
Neil did you forgot some targets when you were doing this change?
