[L2Ork-dev] Potential Gem bug?

IOhannes et al.,

I just checked out the latest Gem (0.94 branch) by doing:

git clone https://git.code.sf.net/p/pd-gem/gem pd-gem-gem

When starting pd-l2ork, it segfaults with the following backtrace. Any idea
what may be wrong? Is this a stable branch?

Also, on a related note, I am wondering how come the git submodule inside
pd-l2ork still pulls 0.93 when the command above does 0.94?

pd-l2ork's .gitmodule has:

[submodule "Gem"]
path = Gem
url = git://git.code.sf.net/p/pd-gem/gem
