           Summary: ICE in build_unary_op, at c-typeck.c:3786
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: etienne_lorrain@yahoo.fr

The file which produces the ICE

If I type (locally generated libmpc and libgmp):
LD_PRELOAD=/home/etienne/projet/toolchain/lib/libmpc.so:/home/etienne/projet/toolchain/lib/libgmp.so
/home/etienne/projet/toolchain/bin/gcc  main.i
with the attached main.i, I get two warnings and:
main.c: In function âis_valid_chgmode_keycodeâ:
main.c:2575:3: internal compiler error: in build_unary_op, at c-typeck.c:3786
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

I am not sure I have generated perfectly gcc-4.6.0 - first time I generate this
version,
but I used to be able to generate gcc-4.5.* and compile that file.
