Bug ID: 85229
Summary: .[concepts] ICE with local class in lambda
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
Blocks: 67491
Target Milestone: ---
The following invalid code snippet (compiled with "-fconcepts")
triggers an ICE since GCC 6.1.0 (when concepts were introduced):

{
struct A
{
C{T} void foo();
};
};
=========================================
