[PR fortran/60126] Internal compiler error with code using pointer reshaping (gfortran 4.8.2)

[Harald Anlauf]

Hello,

the above bug appears to have been fixed over 2.5 years ago.
It does not trigger with 4.9, 5 and 6 trunk, but does with 4.8.0 and
before.

I recommend to close the bug, while adding a testcase to the trunk's
testsuite.  See e.g. the attached example.
