generated with the help of perlbug 1.34 running under perl v5.8.2.

[Please enter your report here]
aassign to a hash has some problems in list context:
$ perl5.8.2 -wle'our %x; print join ":",%x=(1)x8'
Use of uninitialized value in join or string at -e line 1.
1::1:1:1:Use of uninitialized value in join or string at -e line 1.
:1:1
$ perl5.8.2 -wle'print [%x=(1)x8]'
Name "main::x" used only once: possible typo at -e line 1.
Bizarre copy of ARRAY in anonlist at -e line 1.
$ perl5.8.2 -wle'use Devel::Peek; Dump $_ for %x=(1)x8'
Name "main::x" used only once: possible typo at -e line 1.
