See also PR 29572 (matmul(a,b) and matmul(a,transpose(b))).
sunf95 and NAG f95 catch this PR and also PR29572 and also pack().
g95 catches this PR and matmul(a,b), but not matmul(a,transpose(b))).

Postscriptum:
sunf95 already finds the problem in the program check at compile time.
For non-intrinsics (non libgfortran) routines, one way to do it is too do it in
the function called. (Internally called as foo

Well, I get a bounds violation with current versions of g95 (0.91)
on both Linux and Cygwin:
