Merge branch '10.0' into bb-10.1-merge
|
The crash only happens if TokuDB is enabled.
Out of two machines I tried (Precise and Wheezy), it happens on Precise but not on Wheezy; maybe because the versions of libjemalloc* are different there, or could be some other reason.

It has just occurred to me, do you mean server crashes in buildbot? Or in your own Precise VM where you've built MariaDB with system jemalloc 2.2.5?
If the latter, the fix could be — don't use jemalloc if it's older than 2.3
Neither. I mean perro. I suppose we should just upgrade jemalloc there.
Yes, I believe I've seen it. This is why our Precise builder has jemalloc 3.6.0. I've even written in KB
In 10.0 we've linked with jemalloc statically, in 10.1 we link with it dynamically (
MDEV-6895). I suppose that's why 10.0 binaries work on Precise (using jemalloc 3.6.0 they were linked with) and 10.1 binaries crash (using system jemalloc 2.2.5).We either need to link with jemalloc statically on Precise, or use a versioned jemalloc dependency in .deb files.
