Package: libparams-classify-perl
Version: 0.013-6+b1
Severity: important
Tags: patch upstream
The XS version of this package registers an op checker by writing directly into
PL_check array
(see libparams-classify-perl-0.013: lib/Params/Classify.xs line 741)
This is not the canonic way of registering a op checker, it should use
wrap_op_checker instead.
This bug is only causing problem if the BOOT section is executed twice : on the
second
execution, the infinite loop will form when nxck_entersub will point to
myck_entersub (as PL_check[OP_ENTERSUB] already points to myck_entersub).
Note: the bug is fixed in version 0.015 (buster).
