[debian-mysql] Bug#1030510: Info received (mariadb: FTBFS on s390x: timeout)

Mon Feb 6 06:00:01 GMT 2023

Control: retitle -1 mariadb: FTBFS on s390x: crash on munmap(),
free(), aligned_free()

For the record, the latest build
https://buildd.debian.org/status/fetch.php?pkg=mariadb&arch=s390x&ver=1%3A10.11.1-3&stamp=1675662468&raw=0
shows other test failures again, but the stack trace seem to have
munmap(), free(), aligned_free() etc in common:

Attempting backtrace. You can use the following information to find out

 - found 'core' (0/5)
Core generated by '/<<PKGBUILDDIR>>/builddir/sql/mariadbd'
Output from gdb follows. The first stack trace is from the failing thread.
The following stack traces are from all threads (so the failing one is
duplicated).
