[LAD] ambix vs JUCE, segfault

[Fernando Lopez-Lezcano]

Anyone out there using ambix on Linux?

I'm seeing various instabilities, for example trying out the converter 
standalone I get a segfault when connecting output ports, and it looks 
like the Jack JUCE component is doing some unaligned memory copies.

Any hint on how to fix this?

I get Ardour crashes if I try to use the converter LV2 plugin as well.

See below for a trace of the standalone binary...
Thanks for any help!
