This is amazing. The issue has showed up a second time in a row in
bowerbird, as of:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=bowerbird&dt=2022-08-29%2013%3A30%3A32
I don't know what to think about ASLR that manipulates the comment in
this XML object under VS 2017 (perhaps a compiler issue?), but it
should be possible to go back to green simply by removing "<!--c1-->"
from the input string. Creating an extra output pattern here would be
very costly, as xml_2.out and xml.out have outputs for --with-libxml.
Would people object if I do that for now?
