Bug ID: 109139
Summary: ice in make_decl_rtl, at varasm.cc:1442
Product: gcc

This C code:
const int COMPARE_CANDIDATE;
char ipmi_ek_compare_link_record1_0, ipmi_ek_compare_link_record2_0;
void ipmi_ek_compare_link() {
for (; ipmi_ek_compare_link_record1_0;)
for (; ipmi_ek_compare_link_record2_0;) {
int link[COMPARE_CANDIDATE];
}
}
when compiled by today's gcc trunk, does this:
$ ~/gcc/results.20230315/bin/gcc -c -w -O1 -ftrivial-auto-var-init=zero
bug896.c
during RTL pass: expand
bug896.c: In function ‘ipmi_ek_compare_link’:
bug896.c:6:11: internal compiler error: in make_decl_rtl, at varasm.cc:1442
