Interesting perl compilation problem

[John Klos <john%ziaspace.com@localhost>]

Hi,

I think this is just strange, so I figured I'd put it out there. When 
trying to compile pkgsrc/lang/perl5 on various m68k machines, I'm getting 
different results. On an m68040 mac68k machine and on one m68060 Amiga, 
I'm seeing success (in spite of warnings):

`sh  cflags "optimize='-O2 -O2 -m68040 -pthread -I/usr/include'" toke.o` -DPIC 
-fPIC toke.c
          CCCMD =  cc -DPERL_CORE -c -fno-strict-aliasing -pipe 
-I/usr/local/include  -std=c89 -O2 -O2 -m68040 -pthread -I/usr/include 
-Wall -ansi   -W -Wextra -Wdeclaration-after-statement -Wendif-labels -Wc++-compat

or

`sh  cflags "optimize='-O2 -pthread -I/usr/include'" toke.o` -DPIC -fPIC toke.c
          CCCMD =  cc -DPERL_CORE -c -fno-strict-aliasing -pipe 
-I/usr/local/include  -std=c89 -O2 -pthread -I/usr/include -Wall -ansi

On another m68060 Amiga, it failed:

`sh  cflags "optimize='-O2 -O2 -m68060 -pthread -I/usr/include'" toke.o` 
-DPIC -fPIC toke.c
          CCCMD =  cc -DPERL_CORE -c -fno-strict-aliasing -pipe 
-I/usr/local/include  -std=c89 -O2 -O2 -m68060 -pthread -I/usr/include 
-Wall -ansi   -W -Wextra -Wdeclaration-after-statement -Wendif-labels 
-Wc++-compat
toke.c: In function 'Perl_yylex':
toke.c:6909: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.NetBSD.org/Misc/send-pr.html> for instructions.
*** Error code 1

However, for toke.o, if I drop the optimization level down to -O, it 
compiles. It doesn't compile with -O2 even if I unlimit, but it compiles 
without unlimiting on the mac68k machine and the other Amiga.

All three systems are running NetBSD 5 from a few days ago. The Amiga 
which succeeds has 128 megs of memory (Amiga 4000 with Cyberstorm), and 
the Amiga which fails is an Amiga 1200 with 256 megs (Blizzard 1260).

Interesting, huh?
