ICE in dwarf2out.c, egcs-2.92.11 19980921

[Peter Nordlund]

For a long time there has been problems with the Blitz++-package on 
SGI Octane.
Internal error in dwarf2out.c has occurred when compiling the testsuite
with -g as long as I remember.
Now I have reduced the code to the following program.
I hope that someone understands what is causing the ICE.

Due to a known bug in the last snapshot I patched the
egcs-19980921/gcc/Makefile.in in
the following manner: (I hope this was the right way to do it?)

diff /usr/local/cvap/egcs/src/egcs-19980921/gcc/Makefile.in

< TCFLAGS = -fno-weak
< CFLAGS = -fno-weak -g @stage1_warn_cflags@

> XCFLAGS =
> TCFLAGS =
> CFLAGS = -g @stage1_warn_cflags@

I have attached the ii-file in the mail. 
(It doesn't look interesting to me.)
