=================OUTPUT=========================
clang.EXE: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 3.8.0 (cfe/trunk 243859)
Target: x86_64-pc-windows-msvc
Thread model: posix
clang.EXE: note: diagnostic msg: PLEASE submit a bug report to
<a href="http://llvm.org/bugs/">http://llvm.org/bugs/</a> and include the crash backtrace, preprocessed source, and
associated run script.
clang.EXE: note: diagnostic msg:
=================EXTRA INFORMATION==================
In this case Clang fails with a segmentation fault after a nested return of
lamda-functions. Note, that it can be reproduced only on Windows, because on
Linux this code is correctly compiled. Line#1 is compiled correctly without a
call of function x() even on Windows. But after trying to initialize a new
variable with a return value of this lambda function, compiler fails with
segmentation fault.
