Thomas pointed out to me that thorntail also failed, and that it included a backtrace. Unfortunately it's not somewhat confusing. The innermost frame is: #0 0x00000100006319a4 in bbsink_archive_contents (len=<optimized out>, sink=<optimized out>) at /home/nm/farm/sparc64_deb10_gcc_64_ubsan/HEAD/pgsql.build/../pgsql/src/backend/replication/basebackup.c:1672 1672 return true; Line 1672 of basebackup.c is indeed "return true" but we're inside of sendFile(), not bbsink_archive_contents(). However, bbsink_archive_contents() is an inline function so maybe the failure is misattributed. I wonder whether the "sink" pointer in that function is somehow not valid ... but I don't know how that would happen, or why it would happen only on this machine. -- Robert Haas EDB: http://www.enterprisedb.com
