<div dir="ltr">In follow-up to this, it appears that 14.04 Ubuntu 64bit works just fine with the latest flext and fluid~ whereas the same code base crashes on 16.04 64bit.

It worked perfectly fine before. The backtrace is fairly cryptic suggesting something is wrong with the libfluidsynth. Yet, other apps that use it work just fine (e.g. Qsynth). To make matters more complicated, fluid~ uses flext library, although other externals work fine with the current version of flext.</div><div><br></div><div>Below is the gdb backtrace:</div><div><br></div><div><div>#0 0x0000000000000000 in ??
