lmms hangs when render a project to wav file via command line

[ycollet]

I use lmms compile from git repo (master branch at commit 2f969c1) on fedora 21 64 bits.
I use lmms from command line to export a project to WAV:

lmms -r 01_tardive.mmpz -o 01_tardive.wav -f wav

When this command line is used, lmms hangs:

[ycollet]

Tested with lmms-1.1.3 compiled from sources and it works fine here.

Thanks for reporting this. This error seems to be caused by #2049.

[ycollet]

And maybe also #2035.

This would have been fixed in #2118
