libtest-memory-cycle-perl - 1.06-2 main

Test::Memory::Cycle checks for memory leaks and circular memory
references. It's a thin Test::More-compatible wrapper around Lincoln
Stein's Devel::Cycle module.
.
Perl's garbage collection has one big problem: Circular references
can't get cleaned up. A circular reference can be as simple as two
reference that refer to each other. Test::Memory::Cycle is built on
top of Devel::Cycle to give you an easy way to check for these
circular references. You can also use memory_cycle_exists() to make
sure that you have a cycle where you expect to have one.
