Bug ID: 83376
Summary: ICE in LTO streamer
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: andi-gcc at firstfloor dot org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Don't have a small test case right now, but will bisect
When building Linux kernel LTO with gcc 8 I currently get an ICE. Doesn't
happen on 7 and I think it's also recent on 8.
In this case data_in->current_decl_data is NULL while reading a reference.
