-fno-strict-aliasing also fixes the issue ...

Cleaned it up into a self-contained repro. Simply compiling with `gcc -O2 -o
test test.c && test` gives a segfault. -O1 or -fno-schedule-insns
-fno-schedule-insns2 avoids the issue.

This whole codebase is complex, and the problem is in btree code which is hard
to simplify down. Best I can do right now is this. First grab the lv2.tar.gz
attachment and extract it into /tmp. Then:
$ git
