Bug ID: 92251
Summary: [10 regression] SEGV in ipa_get_cs_argument_count
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: hubicka at gcc dot gnu.org, marxin at gcc dot gnu.org
Target Milestone: ---
Target: i?86-*-*, sparc-*-*, ia64-*-*, powerpc64le-*-*,
s390x-*-*, x86_64-*-*
Between 20191026 (r277475) and 20191027 (r277487), a Go test regressed
(I'm seeing it on both 32 and 64-bit Solaris/SPARC and x86, with several more
reports on Linux/x86_64 and several others):
+FAIL: go.test/test/fixedbugs/bug407.dir/one.go -O (internal compiler error)
+FAIL: go.test/test/fixedbugs/bug407.dir/one.go -O (test for excess errors)
Excess errors:
during IPA pass: inline
go1: internal compiler error: Segmentation Fault

This is almost certainly due to one of the IPA patches in that range.
