Bug ID: 91712
Summary: [10 regression] ICE in bind_field_or_method, at
go/gofrontend/types.cc:11878
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: ro at gcc dot gnu.org
CC: cmang at google dot com
Target Milestone: ---
Target: i386-pc-solaris2.11, sparc-sun-solaris2.11
After the Go 1.13 Beta 1 import, mainline bootstrap failed on Solaris as
described in https://gcc.gnu.org/ml/gcc-patches/2019-09/msg00464.html.
With the patch posted there, I managed to restore bootstrap. However, one
libgo testcase regressed on both sparc and x86:
