On Perl 5.17.9, t/apache/read2.t fails because an "uninitialized value" warning is generated for the buffer being autovivified. This is because the sv_setpvn() that's meant to vivify the buffer doesn't perform set magic; the warning is generated by the immediately following SvPV_force(). Patch to fix this from rt.cpan.org #83922. [Zefram]
