m2o fails on Ubuntu 16.04 when used with Sonic Pi midi

[jhw]

I am using the latest osmid commit 72538fe596c404904f9a5b49cbc617121487f89 [Fri Jun 23 11:17:45 2017 +0100] and recent Sonic Pi commit a8cbd26c8022bb80a189fea025bf84edb546c17 [Sun Jun 25 09:52:59 2017 +0000]

When testing Sonic Pi midi I notice that the m2o process dies with a segmentation fault and no sound is heard from my Fluid softsynth (midi device)

If I try running m2o from the command line I get the following, ultimately returning a segmentation fault; looks to me like there is some kind of infinite loop with respect to midi port lookup

Many thanks

FWIW this sounds very much like the problem @rbnpi had with the Raspberry Pi a few days ago, but which got fixed. Is it possible Ubuntu needs a slightly different fix ?

No-one ? Closing :-(

Hi, not sure what problem Robin was having... can you point me to it and I'll have a look.

Apologies for missing this. I am quite busy lately...
