Subject: [PATCH] multi_linestring2perl: only extend the array if needed
|
|
|
|
When the size is 0, we end up extending the stack with
|
|
a negative value. As of Perl 5.19.4, more precisely
|
|
http://perl5.git.perl.org/perl.git/commit/fc16c3924bd6aa054f21ad5445fecf9b7f39dc36
|
|
this ends up allocating memory for 4G-1 elements.
|
|
