Running gmtime("NaN"); in void or scalar context causes a segmentation fault
[0][email protected]:~$ perl -e'gmtime("NaN")'
Segmentation fault
[139]suppy@luna:~$ perl -e'$foo = gmtime("NaN")'
Segmentation fault
[139]s[email protected]:~$ perl -e'@foo = gmtime("NaN")'
[0][email protected]:~$
This appears to happen on all released perls since 5.12 (inclusive):
[0]suppy@luna:~$ for perl in ~/perl5/perlbrew/perls/perl-*/bin/perl;
do $perl -v | grep "This is perl"; $perl -e'gmtime("NaN")'; echo "^ -
