Devel::LeakTrace - indicate where leaked variables are coming from.

  perl -MDevel::LeakTrace -e '{ my $foo; $foo = \$foo }'
  leaked SV(0x528d0) from -e line 1
  leaked SV(0x116a10) from -e line 1

Based heavily on Devel::Leak, Devel::LeakTrace uses the pluggable runops feature found in perl 5.6 and later in order to trace SV allocations of a running program.

At END time Devel::LeakTrace identifies any remaining variables, and reports on the lines in which the came into existence.

Note that by default state is first recorded during the INIT phase. As such the module will not pay attention to any scalars created during BEGIN time. This is intentional as symbol table aliasing is never released before the END times and this is most common in the implicit BEGIN blocks of use statements.

glib is used for it's hash manipulation routines to keep state. This is an external dependency that is hoped can be removed, but tuits as yet haven't presented themselves.
