Re^4: Advice wanted for debugging CPAN Testers failures

[pryrt]

I'd be interested to see 2 reports indicative of that.

The two reports linked in my original post: both showed linux 3.16.0-4-amd64 debian 3.16.7-ckt25-2 (2016-04-08) with gccversion='4.9.2', libc=libc-2.19.so, and gnulibc_version='2.19', the only difference being 5.20.1 vs 5.22.0. But as stevieb replied, it's probably the improved NaN handling in 5.22 which fixed the bug. (Which then surprises me that my ancient linux perl v5.8.5 passed... but then again, there were probably other NaN handling changes in Perl or differences between the systems/compilers).

Interesting. I didn't realise that perl had got actively involved in standardising the signedness of NaNs.
Thanks for the heads up stevieb, pryrt.

Cheers,
