Bug ID: 79765
Summary: [CHKP] ICE in create_target_clone in
multiple_target.c:211
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: ienkovich at gcc dot gnu.org
Target Milestone: ---
Looks multiversioning is not happy to be combined with MPX:
$ gcc /home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/mvc4.c -mmpx
-fcheck-pointer-bounds
/home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/mvc4.c:27:1:
internal compiler error: Segmentation fault

Started when multiversioning was introduced. I'll take a look.
