[Bug fortran/28849] Missed array shape violation with RESHAPE despite -fbounds-check

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 (&parm.5, D.1358);)
That way one could even detect the problem if one moves the "foo" function out
of the "program" and uses an "interface". In this case neither sunf95 nor
NAGf95 find the error.

But what would be the best way for the library? Adding a check version to it?
Adding a if(flag) to it (may slow down)? Both NAG f95 and sunf95 seem to expand
those intrinsics (pack, reshape, transpose) rather than using a library call
and add then the check directly in the tree.
