ICE in extract_insn with gcc-20040620

[Tim Janik <timj at gtk dot org>]

hi Matthias and gcc team,

i'm mailing you because i ran into an ICE with the debian unstable
package of gcc-3.5, specfically gcc-snapshot_20040620-1_i386.deb:

 gcc-snapshot (20040620-1) unstable; urgency=low

   * CVS 20040620, taken from HEAD (gcc-3.5).

i'm not sure whether that package is a stock compiler from
CVS or if additional patches are applied and if the ice can simply
be reproduced with a recent CVS version, so the report goes to
matthias and the gcc-bugs team.

i could reproduce the ice under two distinct x86 machines with
linux-2.4.20 and linux-2.6.6, libc-2.3.2 on both systems.

aparently, -ftracer triggers an ice in extract_insn with the
attached preprocessed source, the exact output is:

$ /usr/lib/gcc-snapshot/bin/gcc -ftracer -c ice1.c
sfiglue.c: In function `sfi_glue_gc_run':
sfiglue.c:880: error: unrecognizable insn:
(jump_insn 92 91 93 4 (return) -1 (nil)
    (nil))
sfiglue.c:880: internal compiler error: in extract_insn, at recog.c:2068
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.


let me know if you need any further information.
