           Summary: IRIX 6.2 bootstrap failure: ICE in expand_increment
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: bootstrap
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ro at techfak dot uni-bielefeld dot de
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: mips-sgi-irix6.2
  GCC host triplet: mips-sgi-irix6.2
GCC target triplet: mips-sgi-irix6.2

The stage1 cc1 ICEs building libgcc/_muldi3.o on IRIX 6.2:

/vol/gnu/src/gcc/gcc-dist-current/gcc/libgcc2.c: In function `__muldi3':

/vol/gnu/src/gcc/gcc-dist-current/gcc/libgcc2.c:502: internal compiler error: tree check: accessed operand 4769025 of error_mark with 0 operands in expand_increment, at expr.c:9587
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make[3]: *** [libgcc/./_muldi3.o] Error 1

Environment:
System: IRIX lynx 6.2 03131015 IP22


	
host: mips-sgi-irix6.2
build: mips-sgi-irix6.2
target: mips-sgi-irix6.2
configured with: /vol/gnu/src/gcc/gcc-dist-current/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --disable-multilib

How-To-Repeat:
Bootstrap current mainline with gcc (3.1 in this case).  The same bootstrap
works on IRIX 6.5.21.

The failure even occurs with ./cc1 libgcc2.i.
