Bug ID: 109723
Summary: [14 regression] ICE in instantiate_decl, at
cp/pt.cc:27066 when building opencv-4.7.0
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
Created attachment 54987
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54987&action=edit
bimef.cpp.ii.xz
This may be a dupe of PR109645 or PR109658, not sure, but I figure it's worth
the test case anyway even if it is.
Hit this when building opencv-4.7.0 with gcc 14.
