Bug#786438: libmp3lame0: general protection error in libmp3lame.so.0.0.0

[Bernhard Übelacker]

Hello Fabian,
can confirm that both variants are fixing the issue.

I would prefer the function level fix, but as there is already a change 
to the build system that does exclusively apply to this file, I think 
both are equally good.

(And when OCaml 4.02 enters Stretch we can try removing it again.)

Kind regards,
Bernhard
