Bug ID: 109643
Summary: [14 Regression] IPA inline ICE on pkg-config-0.29.2
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: slyfox at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Noticed ICE on pkg-config-0.29.2 when was building with gcc from master.
Minimal example:
//$ cat bug.c.c
int g_variant_type_info_basic_table[1];
int g_variant_type_info_check__g_boolean_var_, g_variant_type_info_get_index;
int *g_variant_type_info_get_info;
int g_assertion_message_expr();
void g_variant_type_info_check(int *info) {
int index = info - g_variant_type_info_basic_table;
if (index)
g_variant_type_info_check__g_boolean_var_ = 1;
g_assertion_message_expr();
}
void g_variant_type_info_get() {
g_variant_type_info_get_info =
g_variant_type_info_basic_table + g_variant_type_info_get_index;
g_variant_type_info_check(g_variant_type_info_get_info);
}
Crash:
$ gcc -c bug.c.c -o bug.o -O2
during IPA pass: inline
bug.c.c:15:1: internal compiler error: Segmentation fault
