Bug ID: 81607
Summary: Conditional operator: "type mismatch in shift
expression" error
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: babokin at gmail dot com
Target Milestone: ---
gcc trunk, rev250630, x86_64.
I see a lot of crashes involving conditional operator and struct field access.
I see at least 7 different kind of crashes. They may be related, so I'm filing
only this one for now to avoid spamming the bug tracker. After fixing this one,
I'll proceed with others if they are not fixed.
