Bug ID: 48869
Summary: gcc 5.3: fails with error: implicit instantiation of
undefined template
'std::hash<lldb_private::ScratchTypeSystemClang::Isola
tedASTKind>'
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: release blocker
Priority: P
Component: All Bugs
Assignee: lldb-dev at lists.llvm.org
Reporter: sylvestre at debian.org

In theory, llvm should support gcc from version 5.1:
https://llvm.org/docs/GettingStarted.html#software
but it fails to build using 5.3.1, the version of gcc on Ubuntu Xenial (a LTS).
I think the regressor is https://reviews.llvm.org/D92759
apt.llvm.org for xenial has been broke since Dec 10
Full error:
