Bug ID: 85101
Summary: C++17 ICE in build_over_call, at cp/call.c:8149
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: proski at gnu dot org
Target Milestone: ---
Today's gcc source from git. C++17 and C++2a are affected, C++14 is not. I was
able to compile that code with the latest (at the time) gcc snapshot about a
month ago, so it's probably a recent regression. gcc 7.3.1 can compile the
code.
Fedora 27 x86_64, all up-to-date, gcc compiled from git and installed to
/opt/gcc
$ /opt/gcc/bin/g++ -v
Using built-in specs.
