Dear Paul,

If I compile the test with -fsanitize=address,undefined I get at run time

Dear All,

The recent patches on trunk to gfc_trans_allocate have fixed PR67933.
I have added a testcase, which has been committed as revision 229452.

Since this is a 4.9/5 regression, I will extract the minimum change
necessary and will submit it as soon as I have regtested.

Cheers

Paul
