In the official tree, there is a branch 'maint-v0.6.2' which just contain
4 patches fixing some problems with the release v0.6.2, the second patch
77f35b796cc8 ("generic: fix missing inlining of generic expression")
being the one fixing this problem.
For info, I'll most probably make a new full release in a few weeks
(rc1 in 7-10 days, release 1-2 weeks later).
