[Bug fortran/27229] New: char_transpose_1.f90 fails with ICE in gfc_conv_array_transpose

[janis at gcc dot gnu dot org]

Test gfortran.dg/char_transpose_1.f90 fails on mainline for
powerpc-unknown-linux-gnu with optimization:

/home/gccbuild/gcc_trunk_anonsvn/gcc/gcc/testsuite/gfortran.dg/char_transpose_1.f90:9:
internal compiler error: in gfc_conv_array_transpose, at
fortran/trans-array.c:726^M
Please submit a full bug report,^M
with preprocessed source if appropriate.^M

A regression hunt identified this patch:

r112955 | kazu | 2006-04-14 14:31:32 +0000 (Fri, 14 Apr 2006) | 8 lines

        * local-alloc.c (rest_of_handle_local_alloc): Use VEC instead
        of VARRAY.
        * reload1.c (reg_equiv_memory_loc_varray): Rename to
        reg_equiv_memory_loc_vec.  Change the type to VEC(rtx,gc) *.
        (init_reload, reload): Use VEC instead of VARRAY.
        * reload.h: Update the prototype for
        reg_equiv_memory_loc_varray.

That seemed unlikely so I tried reverting that patch from today's mainline, and
it did indeed allow the test to pass.

The same ICE is reported in PR26119, filed 2006-02-06.

I don't see that failure any more (on powerpc64-unknown-linux-gnu). It was
present on 20060423, but disappeared on 20060430.

Janis, do you still see it? (its brother bug, PR 26119, also disappeared)

Very odd; I do nightly builds of mainline on two different systems.  On one of
them this failure stopped on 20060430 and on the other it stopped on 20060503,
but failed on 20060502.

Can this now be closed?

The test passes on both of my nightly builds now, so I'm closing this.
