No, this is not a ubsan report.
Code *crashes* and I thought showing the UBsan warning was enough to
demonstrate it.
A minimal change to make the code crash instead of just report ubsan errors:

Ah, sorry I didn't realize that. Its use was suggested by Jason Turner in his
most recent C++ Weekly so I started to give it a try. Perhaps there will be an

I get a similar warning with this code. Unsure if it's the same underlying
issue. Also does not warn with g++10 or g++11, but does with newer versions.

Thank you for the information. If the equality comparison function is slow
enough, the large number of extra calls may not be an optimization.
While looking into it, the vastly different runtime behavi

Even marginally simpler:

return "_" + std::string(" ");
}
Originally I marked it as tree-optimization since it's only with -O3, but it
could be an issue in the standard library
