Confirmed.
This one is funny. The TRANSPOSE seems to screw up the simplification.
Works without TRANSPOSE.

--- Comment #4 from anlauf at gcc dot gnu.org ---
For reasons I do not understand,
Breakpoint 1, gfc_simplify_matmul (matrix_a=0x292bbf0, matrix_b=0x292c550)
at ../../gcc-trunk/gcc/fortran/simplify.c:4777
4777 result_columns = mpz_get_si (matrix_b->shape[1]);
(gdb) p matrix_b->shape[1]
$64 = {{_mp_alloc = 0, _mp_size = 0, _mp_d = 0x0}}
(gdb) p matrix_b->shape[0]
$65 = {{_mp_alloc = 0, _mp_size = 0, _mp_d = 0x0}}
This is a result from the mpz_set in gfc_simplify_transpose.
Isn't this a representation of zero?
Alternative patch, which passes the relevant regtesting:

OK, now I see it. gfc_get_shape does not init the resulting shape.
The following simpler patch does the job:

I know. But it only covers the issue in gfc_simplify_transpose.
