Re: [fluid-dev] Fluidsynth segfault on gentoo amd64

[Jeremiah Benham]

I recompiled fluidsynth with these options:

./configure  --disable-oss-support --enable-debug  --enable-longlong

I have amd64 in 64bit mode
gentoo
alsa 1.08

What other info do you need?

It still segfaults. Here is a bt full:
