Bug ID: 94479
Summary: NetBSD: internal compiler error: in
recompute_tree_invariant_for_addr_expr
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: tk at giga dot or.at
Target Milestone: ---
When compiling git-2.26.0 with gcc 8.3.0, 8.4.0, or 9.3.0 on NetBSD/amd64 with
-fstack-check, I see (output from 8.4.0):
builtin/rebase.c: In function 'cmd_rebase__interactive':
builtin/rebase.c:473:41: internal compiler error: in
recompute_tree_invariant_for_addr_expr, at tree.c:4487
{ OPTION_CALLBACK, 'k', "keep-empty", &options, NULL,
^~~~~~~~
I used creduce to get a minimal test case, save the following to rebase.i and
run:
# gcc -o rebase.o -c -fstack-check rebase.i
---- begin ----
int a;
struct b {
char c;
void *d;
};
struct b e() {
struct b f[] = {{}, "", f, a};
}
---- end ----
I tried running this in 8.3.0 and 9.3.0 on https://godbolt.org/ (where I had to
add -fpermissive for it to compile) but it doesn't seem to trigger the problem
there. So perhaps it's fine on Linux.
