Here is updated information if you are interested. I realize the
recommendation is probably to move to libc++.
This is using clang++-6.0. Updated test case regex.
clang++-6.0 -std=c++14 -O3 -g test.cpp

Title:
clang++ regex_replace always segfaults with -O3
To manage notifications about this
I think the reduces test case is invalid - std::regex("") - although it
had the same crash signature as the real world crash.
Oh well, sorry for the spam.

Just for historical record for anyone who search this, I was able to
reproduce this with clang 4, 5 and 6.
I can only assume it is an issue with the version of libstdc++-dev
pushed to 16.04.03.
Running the resulting executable always triggers a segmentation fault
with -03 but runs correctly witho
I reported it because it is the default clang installed for 16.04 which
is the only clang we can expect the user to have.

3.8 is pretty old. you should try with a more recent version
(https://apt.llvm.org/ can help with that).
Anyway, I cannot reproduce the issue from 3.8 to 7.
