Current sid does not have the issue any more, please feel free to close
this bug report.

I just ran the whole testsuite (and also did some manual chroot
prepares) on the 1.0.x branch with current sid/amd64 -- could not
produce the problem.

Same libsqlite afaics (/usr/lib/x86_64-linux-gnu/libsqlite3.so.0.8.6).

However, I hope this

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=923038

is the same issue; then it might have been fixed in sqlite3 3.27.2-1
(w/o updating the so version)...

Could you recheck?

Thx!

Package: mini-buildd
Version: 1.0.36
Severity: important

Hi,

I log in to my mini-buildd instance, start configuring, call up the Dir
chroots, mark one, click on "prepare". The browser immediately returns a
"connection reset", no mini-buildd process is there any more, and the
syslog shows:

Feb 19 11:27:10 spinturn kernel: mini-buildd[1368]: segfault at 8 ip

'signal'.

spinturn is an amd64 box, but the same thing (sans the kernel messages,
but that might be a logging/klog issue) happens also on armhf.

I guess this might have something to do with the recent sqlite update,
maybe a recompile of the sqlite-related libraries can fix that.

Greetings
Marc
