Description
This is a bug report for perl from [email protected],
generated with the help of perlbug 1.41 running under perl 5.30.1.
[Please describe your issue here]
perl-5.30.1 segfaults when running this (much simplified) code:
@N = 1..5;
map { pop @N } @N;
Using a debugging perl gives:
perl: sv.c:6567: Perl_sv_clear: Assertion `SvTYPE(sv) != (svtype)SVTYPEMASK' failed.
Aborted (core dumped)
The only other recent perl I have installed is strawberry perl-5.30.0
on windows 10 which does not segfault.
[Please do not change anything below this line]
Flags:
category=core
