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).
