Bug ID: 88573
Summary: 9 regression: error: type mismatch in component
reference
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: andi-gcc at firstfloor dot org
Target Milestone: ---
Don't have a small test case currently, happens during a large LTO Linux kernel
build.
With gcc trunk (20181222) with checking enabled I get
/home/ak/lsrc/linux/kernel/events/callchain.c: In function
'get_callchain_entry':
/home/ak/lsrc/linux/kernel/events/callchain.c:260:1: error: type mismatch in
component reference
260 | }
| ^
struct perf_callchain_entry *[0:]
struct perf_callchain_entry *[0:]
_3 = entries->cpu_entries[cpu];
during IPA pass: *free_lang_data
/home/ak/lsrc/linux/kernel/events/callchain.c:260:1: internal compiler error:
verify_gimple failed
gcc 8 doesn't show this problem.
