Text::CSV_XS versions before 1.62 for Perl have a use-after-free
when registered callbacks extend the Perl argument stack, which may
enable type confusion or memory corruption.
The Parse, print, getline, and getline_all methods invoke registered
callbacks (for example after_parse, before_print, or on_error) and
cache the Perl argument stack pointer across the call. If a callback
extends the argument stack enough to trigger a reallocation, the
return value is written through the stale pointer into the freed
buffer, and the caller reads the original $self argument as the
return value instead.
Calling code that expects parsed data from getline_all receives the
Text::CSV_XS object in its place, leading to logic errors or crashes.
Text::CSV_XS objects used without any registered callbacks are not
affected.
