gcc 2.95.2 objc bug on IRIX 6.2 with -g

[Tim Waggett <tim dot waggett at asa dot co dot uk>]

Tried to use GNATS - got a "redirecting - please wait" message and got
bored after a few minutes.


GCC VERSION AND SYSTEM TYPE:
gela:141# gcc -v
Reading specs from
/usr/freeware/lib/gcc-lib/mips-sgi-irix6.2/2.95.2/specs
gcc version 2.95.2 19991024 (release)
gela:142# uname -a
IRIX gela 6.2 03131015 IP20


COMMAND LINE AND OUTPUT:
gela:149# gcc -c -Wall -g break-irix.m
break-irix.m:26: Internal compiler error in `dwarf2out_finish', at
dwarf2out.c:10054
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/faq.html#bugreport> for
instructions.


GCC BUILD OPTIONS:
Not known.
gcc was obtained precompiled for IRIX 6.x from freeware.sgi.com
Try freeware@sgi.com for details.


PREPROCESSED FILE:
See attached break-irix.m file.
Derived from preprocessor output of a more complex file it contains no
preprocessor commands.


COMMENTS:
The combination of a protocol and -g seems to be fatal.

Does not fail if -g is omitted:
gela:150# gcc -c -Wall 
gela:151#   

Does not fail on my Linux (SuSE 6.2) system:
