Also affects other p5.30 ports, like ​p5.30-log-dispatch.

[kencu (Ken)]

these have been found in another ticket somewhere as well. I'll see if I can find it. It occurs because the building clang version is too old.

[ryandesign (Ryan Carsten Schmidt)]

Well in these cases the "building clang" is gcc-4.2.

[ryandesign (Ryan Carsten Schmidt)]

And the clang that build perl was 3.4, judging by #59786.

[jmroot (Joshua Root)]

This specific build is pure perl, so gcc-4.2 is unused and is just what gets picked when libc++ is not needed. The actual bug seems to be in p5.30-time-hires.
