Bug ID: 101281
Summary: [11/12 Regression] ICE with -std=f2003/f2008 and
assumed-rank array
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: error-recovery, ice-on-invalid-code
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
Target Milestone: ---
Created attachment 51094
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51094&action=edit
Compile with -std=f2003 or -std=f2008
Found when working on a BIND(C) character testcase. Can probably be reduced.
The problem seems to be related to assumed-rank arrays and it only occurs (at
least in this testcase) for -std=f2003 and -std=f2008, i.e. it works with
-std=-f2008.
I did see it with GCC 11 and GCC 12 - but GCC 10 also showed:
(null):0: confused by earlier errors, bailing out
For some reasons, it does sometimes not crash with 'f951' in the debugger,
unless I pass '-quiet'
It looks as if some error recovery is failing. In any case:
0x00000000008e6ca6 in gfc_resolve_expr (e=0x270a9f0) at
../../repos/gcc/gcc/fortran/resolve.c:7085
7085 else if (e->symtree != NULL
(gdb) p e->symtree
$1 = (gfc_symtree *) 0x270a9b0
(gdb) p e->symtree->n.sym
$2 = (gfc_symbol *) 0x0
The proc being processed is:
(gdb) p gfc_current_ns->proc_name->name
$9 = 0x7ffff716f258 "a3ar"
Depending how the code is reduced, the ICE is gone. However, I did not try very
hard to reduce the code.
Stacktrace is:
(gdb) p *e
$6 = {expr_type = EXPR_VARIABLE, ts = {type = BT_UNKNOWN,
and all values are 0 except for 'where' and 'symtree'.

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
The main culprit is:
subroutine ar3 (xn) bind(C)
character(len=n) :: xn(:,:,:)
end
and I forgot to mention that 'n' is only implicitly defined - otherwise, there
is not ICE.
