Subject: [Bug fortran/110623] New: Segfault if type-bound procedure function provided for an assumed rank class(*) argument
Date: Tue, 11 Jul 2023 06:51:57 +0000	[thread overview]
Message-ID: <bug-110623-4@http.gcc.gnu.org/bugzilla/> (raw)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110623

            Bug ID: 110623
           Summary: Segfault if type-bound procedure function provided for
                    an assumed rank class(*) argument
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mscfd at gmx dot net
  Target Milestone: ---

Created attachment 55519
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55519&action=edit
testcase

The attached code aborts with a segfault (or some undefined behaviour) in the
line "call p(y%get())". For "call p(x%get())" with x declared as type(t)
instead of class(t), everything seems fine.

This is a variation to bug 100961. I have checked with 13.1 and 14.0 (current
master).

valgrind shows "conditional jump depends on uninitialised value" and "invalid
read" before it aborts.
