Thanks for reporting this, Frank.  As Dave has correctly surmised, you
appear to have at least one of fldigi's configuration settings set to
use the old OSS sound system.  OSS is deprecated -- you should be using
PulseAudio instead -- but regardless of that, you have identified a bug
in fldigi.

I can reproduce the crash also, by trying to enable OSS mixer control in
fldigi as follows:

1. From the fldigi menu, select Configure-->Sound Card-->Mixer to bring up the OSS mixer panel.
2. Enable the "Manage mixer" checkbox.
3. Click "Mic in" to try to enable that selection (alternately click "Line in" to disable, then click it again to try to re-enable it).

I've verified that this results in the same crash you're getting -- I'll
work on fixing the crash.

However, Frank, you should just stop trying to use the OSS Mixer
control.  Please do the following -- it should let you avoid the crash:

1. On the Configure-->Sound Card-->Mixer panel, uncheck the "Manage mixer" option.
2. On the Configure-->Sound Card-->Devices panel, select "PulseAudio".
