libdevel-leak-perl - 0.03-4+b4 main

Devel::Leak has two functions: NoteSV and CheckSV.
.
NoteSV walks the perl internal table of allocated SVs (scalar values) - (which
actually contains arrays and hashes too), and records their addresses in a
table. It returns a count of these "things", and stores a pointer to the
table (which is obtained from the heap using malloc()) in its argument.
.
CheckSV is passed argument which holds a pointer to a table created by
NoteSV. It re-walks the perl-internals and calls sv_dump() for any "things"
which did not exist when NoteSV was called. It returns a count of the number
of "things" now allocated.
