Hello world,
the attached patch fixes a regression introduced by my recent patch for
PR 87689, where the alternate return arguments were not handled
correctly.
Some experimentation resulted in a test case which actually segfaulted
on a normal compiler, instead of just being visible on an instrumened
one. The test case also checks that the alternate return runs
correctly (and uses the "dg-do run" hack :-)
I also checked this with -flto and by inspecting the output of
-fdump-fortran-original.
Thanks to Martin Liska for the bug report.
Regression-tested. OK for trunk?
Regards
Thomas

* trans-types.c (get_formal_from_actual_arglist): If
the actual arglist has no expression, the corresponding
formal arglist is an alternate return.
