Package: perl-debug Version: 5.28.0-1 Severity: normal User: [email protected] Usertags: perl-5.28-transition
I noticed that many of our XS module packages are incompatible with debugperl after being rebuilt for 5.28. Consider: # debugperl -MDateTime -e 'print DateTime->today' panic: XSUB DateTime::_rd2ymd (DateTime.c) failed to extend arg stack: base=55b63e6b3b48, sp=55b63e6b3b80, hwm=55b63e6b3b68 # printf '<AAA>\n<DDD/><CCC><DDD>\n</DDD></CCC>\n</AAA>' | debugperl -MXML::LibXML -e 'XML::LibXML->new->parse_fh(*STDIN)->documentElement->childNodes; ' panic: XSUB XML::LibXML::Node::_childNodes (LibXML.c) failed to extend arg stack: base=561827c61b48, sp=561827c61b68, hwm=561827c61b60 This panic is due to a new -DDEBUGGING check that guards the XS function argument stack, making sure that XS code extends the stack properly when it pushes elements there. However, I believe the check isn't currently working properly when the XS code is built with a non-DDEBUGGING perl.h and then run with a -DDEBUGGING perl build. Will take this upstream once I've investigated it properly. -- Niko Tyni [email protected]
