This is a bug report for perl from pali@cpan.org,
generated with the help of perlbug 1.40 running under perl 5.25.10.
-----------------------------------------------------------------
[Please describe your issue here]
Trying to read values from array @DB::args can lead to perl fatal error
"Bizarre copy of ARRAY in scalar assignment". But missing, incomplete or
possible incorrect value in @DB::args is not a fatal error for Carp.
Carp is primary used for reporting warnings and errors from other modules,
so it should not crash perl when trying to print error message.
This patch safely iterates all elements of @DB::args array via eval { }
block and replace already freed scalars for Carp usage by string
"** argument not available anymore **".
This prevent crashing perl and allows to use Carp module. It it not a
proper fix but rather workaround for Carp module. At least it allows to
safely use Carp.
