Summary
[none]
Details

ExtUtils::Typemaps::STL::List versions before 1.07 for Perl allocate a 32 GiB array on an empty list. The OUTPUT typemaps call av_extend( av, len-1 ). On an empty list, this undeflows, and av_extend will allocate an array with 2^32 slots, leading to memory exhaustion. Note that a similar issue was fixed in ExtUtils::Typemaps::STL::Vector version 1.05.
