Yes OK for trunk and affected branches.
Thanks,

Dear all,
the simplification of the TRANSPOSE of a zero-sized array would lead to
an ICE if the result was used in a subsequent simplification of a MATMUL.
The reason was the lack of the proper initialization of the shape, which
is mpz_t. Use mpz_init_set instead of mpz_set.
Regtested on x86_64-pc-linux-gnu. OK for mainline?
Since this is a regression, backport to all affected branches?
Thanks,
Harald
