hdspmixer segfaults on AMD64

hdspmixer segfaults on AMD64

[Mark Knecht]

Hi,
   I think this may possibly be fixed already but I couldn't find an
associated bug in Mantis. When I run hdspmixer on my AMD64 system
using 2.6.13-gentoo or 2.6.12-gentoo-r9 it segfaults. I'm running
Alsa-1.0.9 mostly:

lightning hdspmixer # emerge -pv alsa-tools alsa-utils alsa-headers
alsa-lib alsa-oss alsa-jack

These are the packages that I would merge, in order:

Calculating dependencies ...done!

lightning hdspmixer #

   Has this been addressed already? If so where in the system is the
fix? I'm sort of at a stand still without hdspmixer. I'm hoping there
is a code drop somewhere that I could build and install by hand if
it's just the hdspmixer app.

Thanks,
Mark

Try ALSA 1.0.10-rc1.

Hi Lee,
   I downloaded alsa-tools-1.0.10-rc1 and built just the hdspmixer app
from that tarball. Same segfault. I have a fairly useless (I think)
back trace. I haven't figured out how to get good symbols. (I'm not a
programmer - sorry!)

Here's what I have so far, the important point being that it segfaults
exactly like the one in 1.0.9.

Thanks,
Mark

Actually before you try upgrading, use gdb to get a backtrace.

$ gdb ./hdspmixer

Then when it crashes do "thread apply all bt" and post the output.

I think you can get a better backtrace by running gdb from the source
directory you compiled the program in.  Also install the debug version
of libfltk if possible.

Anyway it looks like the problem is libfltk related.  Maybe try to
upgrade or downgrade libfltk?

Bingo - Upgrading fltk from 1.1.4 to 1.1.6 fixed the problem.
hdspmixer is up. Time to hook up ADAT cables and see if this puppy
makes noise!

Both 1.0.9 from portage and 1.0.10rc1 from the tarball seem to work
with this new version.

Thanks!

Cheers,
Mark
