perl 5.36 breaks texlive - @mlschroe debugged it to be:

the texlive failure is due to a bug in biber-2.17 (i.e. in texlive). They assign to undef, which is forbidden.

Ok, it is a perl module. It's the test suite that's in ruby.

It's yast2-perl-bindings that needs fixing. It breaks because of the following change in perl:

Reading the string form of an integer value no longer sets the flag SVf_POK. The string form is still cached internally, and still re-read directly by the macros SvPV(sv) etc (inline, without calling a C function). XS code that already calls the APIs to get values will not be affected by this change. XS code that accesses flags directly instead of using API calls to express its intent might break, but such code likely is already buggy if passed some other values, such as floating point values or objects with string overloading.

YPerl::fromPerlScalarToAny contains this:

const char *pv = SvPV_nolen (sv);
if (SvPOK (sv))
{
    val = YCPString (pv);
}

The SvPV_nolen call no longer sets the POK flag, so this no longer works for numbers.

A fix would be to use SvPOK(sv) || SvIOK(sv) || SvNOK(sv) instead.

YPerl::fromPerlScalar also needs fixing
