cdparanoia segfaults

Hi,

when I try to read in a CD from a Plextor CD/RW recorder, I get the following 
output, even with the statically linked binary from your web page:

feldner <at> kermit:~/temp> ./cdparanoia-III-alpha9.8.i386-linux-elf -B 
--force-cdrom-device /dev/cdrecorder --disable-paranoia -vvv "1-"
cdparanoia III release 9.8 (March 23, 2001)
(C) 2001 Monty <monty <at> xiph.org> and Xiphophorus

Report bugs to paranoia <at> xiph.org
http://www.xiph.org/paranoia/

Checking /dev/cdrecorder for cdrom...
        Testing /dev/cdrecorder for cooked ioctl() interface
                /dev/scd1 is not a cooked ioctl CDROM.
        Testing /dev/cdrecorder for SCSI interface
                generic device: /dev/sg2
                ioctl device: /dev/scd1

Found an accessible SCSI CDROM drive.
Looking at revision of the SG interface in use...
        SG interface version 3.2.0; OK.
Speicherzugriffsfehler

Cheers,

Andreas.

Is this equivalent to "segmentation fault" in English or is it some other
sort of memory error?

CDParanoia needs an output ring-buffer

To adequatley use cdparanoia with pipes, it needs an output ring-buffer.
By ring-buffer I mean
1.) A 4meg block of memory
2.) Can be read from and written to at the same time
3.) It protects the cdparanoia process from the block behaviour of the
shell pipe ('|')

I presume this would also increase performance even when writing to a
file on a hard disk, as I have noticed cdparanoia's '.o0O0o.' indicater
jerking when the hdd makes noise (no no, seriously :)

Also, It would be cool if cdparanoia saved DIRECTLY to the flac format.
This can be acheived by the following

 bash$ mkfifo tmp.pipe
 bash$ cdparanoia single track > tmp.pipe &
 bash$ flac -5 tmp.pipe -o cd-track.flac

 Problem is that the FIFO's buffer size is 4K! flac and cdparanoia wont
 run parrelel. the operation can take twice as long as it should.
 cdparanoia pauses reading whilst flac processes.

 The work around is to use cdda2wav, with the -paranoia switch ( I much
 prefer cdparanoia routines to cdda2wav's)
 With cdda2wav you can specify a large 'ring buffer' for output to
 stdout(4megs is usually enough).

 An --output-flac option would be cool, but a ring-buffer for stdout mode
 will make cdparanoia usefull with other formats also.

See verbose options of cdda2wav. You will get CD-TEXT if available.
