Interesting.
Adding an ,only to any of the use, intrinsic :: iso_c_binding statements
avoids the ICE.
However, I get an ICE down to gcc-7, so I am not sure that the reported
regression is accurate.

I don't see this on x86_64-*-freebsd, but I also build with
--enable-checking=yes which may or may not mask issues. I'll note that running
valgrind on `f951 a.f90` yields a long listing which starts with

Draft patch
I couldn't track the exact path of the memory error reported by valgrind, but
the attached patch "fixes" (well, it makes it latent I guess) the problem by
removing from the use statement list the statements that are rejected.

There is a bug in it: new use statements are at the end of the linked list, not
at the beginning.

fortran: Ignore use statements on error [PR107426]
This fixes an access to freed memory on the testcase from the PR.
The problem comes from an invalid subroutine statement in an interface,
which is ignored and causes the following statements forming the procedure
body to be rejected. One of them use-associates the intrinsic
ISO_C_BINDING
module, which imports new symbols in a namespace that is freed at the time
the statement is rejected. However, this creates dangling pointers as
ISO_C_BINDING is special and its import creates a reference to the imported
C_PTR symbol in the return type of the global intrinsic symbol for C_LOC
(see the function create_intrinsic_function).
This change saves and restores the list of use statements, so that rejected
use statements are removed before they have a chance to be applied to the
current namespace and create dangling pointers.

Yes. I was initially targetting master only, but then I figured this was a
regression, so backporting was in order.

fortran: Ignore use statements on error [PR107426]
This fixes an access to freed memory on the testcase from the PR.
The problem comes from an invalid subroutine statement in an interface,
which is ignored and causes the following statements forming the procedure
body to be rejected. One of them use-associates the intrinsic
ISO_C_BINDING
module, which imports new symbols in a namespace that is freed at the time
the statement is rejected. However, this creates dangling pointers as
ISO_C_BINDING is special and its import creates a reference to the imported
C_PTR symbol in the return type of the global intrinsic symbol for C_LOC
(see the function create_intrinsic_function).
This change saves and restores the list of use statements, so that rejected
use statements are removed before they have a chance to be applied to the
current namespace and create dangling pointers.
