Assertion `count == b->dim[0].ubound + 1 - b->dim[0].lbound' failed.
Aborted
The call to MATMUL obviously is erroneous, but a runtime error instead of an
assertation would be preferable in this case.

Confirmed, a runtime error would be better.

Unfortunately, I "lost" the example code and wasn't able to recreate one. I
will attach an example when I come across another one.

Here's an example:
$ cat mm.f90
program main
real, dimension(:,:), allocatable :: a
real, dimension(:), allocatable :: b
allocate (a(2,2), b(3))
call random_number(a)
call random_number(b)
print *,matmul(a,b)
end program main
$ gfortran mm.f90
$ ./a.out
a.out: ../../../../gcc/trunk/libgfortran/generated/matmul_r4.c:173: matmul_r4:
Assertion `count == b->dim[0].ubound + 1 - b->dim[0].lbound' failed.
Aborted
