[Bug tree-optimization/22159] New: gcc-4.1-20050618 ICE's during compilation of nbench-byte-2.2.2 file nbench0.c

[Ralf_Recker at gmx dot de]

Program:

nbench-byte-2.2.2.tar.gz

Command (ripped from the Makefile):

# The used compiler
CC = /opt/gcc-4.1-20050618/bin/gcc

# The used options for the compiler
CFLAGS = -s -static -Wall -O3 -fomit-frame-pointer

Error Message:

nbench0.c: In function 'main':
nbench0.c:66: internal compiler error: in tree_verify_flow_info, at tree-cfg.c:3716
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make: *** [nbench0.o] Error 1

Preprocessed source:

Nope (nbench0.i > 100K)

Other GCC snapshots:

gcc-4.1-20050604 and gcc-4.1-20050611 work fine.

Other remarks:

If I add the option -fno-inline-functions the compilation finishes
successfully with gcc-4.1-20050618 =>

It seems to me that the tree-inliner is a candidate for the bug hunt.

Should be fixed already by:
2005-06-20  Jan Hubicka  <jh@suse.cz>

        * cfgloop.h (DLTHE_RECORD_COPY_NUMBER): New flag.
        * cfgloopmanip.c (duplicate_loop_to_header_edge): Set aux flags only
        when asked for.
        * loop-unroll.c (peel_loop_completely, unroll_loop_constant_iterations,
        unroll_loop_runtime_iterations, peel_loop_simple, unroll_loop_stupid):
        Update call of duplicate_loop_to_header_edge.
        (apply_opt_in_copies): Clear out aux pointers.

Can you try a CVS or attach the preprocessed source?
