Bug ID: 42898
Summary: Clang compiler crashes
Product: clang
Version: 6.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++17
Assignee: unassignedclangb...@nondot.org
Reporter: ag...@agner.org

Test case
The attached test case makes clang crash.
The error is detected on Clang version 6.0.0-1ubuntu2 under Windows subsystem
for Linux, Win 10.
The error does not occur under Cygwin64.
clang: error: unable to execute command: Segmentation fault (core dumped)
clang: error: clang frontend command failed due to signal (use -v to see
invocation)
Complete crash report is included as a comment in test.cpp
Command line: clang -m64 -std=c++17 -O2 -mavx test.cpp
I cannot produce a minimal test case because the error disappears even when I
remove seemingly irrelevant code.
