Public bug reported: Ubuntu patched perl to work around a libc compatibility issue, but there is a problem.
Please see the perl bug report at https://rt.perl.org/Public/Bug/Display.html?id=132631 Here is an excerpt from the linked-to perl bug: ...the relevant Ubuntu change: http://deriv.debian.net/patches/p/perl/Debian_perl_5.26.0-8_Ubuntu_perl_5.26.0-8ubuntu1.debian.patch Ubuntu's adding zero to SIG_NUM looks wrong and the probable cause of this bug to me. SIGUNUSED is 31 (alias for SIGSYS) on at least all the Debian architectures where it exists in the first place, and Perl_magic_setsig() gives the warning reported here ('No such signal') when the signal number is zero or negative. So I think this can only be fixed in Ubuntu, and presumably somebody needs to file a Ubuntu bug for that to happen.
