[buildfarm related] Machines gcc experimental failed test_lfind

Hi hackers,

Sorry if it has already been discussed somewhere.

While seeing the buildfarm, I found that recently regression test for modules
sometimes failed [1]. Typical example is [2] and failed at simd.h.
The issue happened over branches, and they use gcc experimental. Based on that
I felt recent commits for gcc might be related with.

I don't have enough knowledge around here, but I saw commits in gcc and listed
Candidates [4], [5], [6]. Can you find something from here?
Also, what should we do for nightly-built compilers? Will we fix tests or codes for them?
