This is probably the same problem as previously reported here​:

https://rt-archive.perl.org/perl5/Ticket/Display.html?id= (sprintf2.t subnormal %a
failures on g++ 6.2)

https://rt-archive.perl.org/perl5/Ticket/Display.html?id=131388 (g++ vs subnormals
in 5.26.0)

Thank you very much.

Would it be possible for you to bisect this? If you need instructions, we can provide them.

[Please describe your issue here]

This is actually for 5.26.2.

The perl testsuite fails in t/op/sprintf2.t​:

That should have been​:

failures on g++ 6.2)

https://rt-archive.perl.org/perl5/Ticket/Display.html?id=131388 (g++ vs subnormals

Thank you very much.
