Hi All,

I downloaded from CVS and built a debug build.  I found this from gdb:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1208461632 (LWP 9706)]
process_rt_event (csound=0x994f008, sensType=0) at Engine/musmon.c:769
769           if (SR(chnrfd) && (rfd = SR(chnrfd)[mep->chan+1])) { /*
RM: USE CHAN + 1 */
(gdb) print mep
$1 = (MEVENT *) 0x9979568
(gdb) print mep->chan
$2 = 0
(gdb) print csound->remoteGlobals
$3 = (void *) 0x0
(gdb) q


It seems the if statement here doesn't check if csound->remoteGlobals
== NULL.  I changed the code to this locally:

      if (csound->remoteGlobals && SR(chnrfd) && (rfd =
SR(chnrfd)[mep->chan+1])) { /* RM: USE CHAN + 1 */

and that fixed it up.  Since this code is actively being worked on by
others and since i don't know if this is the best fix, I'll defer to
others to check in.

Thanks!
steven

BTW: This is the first time I've debugged with a project that uses
wave files. For debugging this, I had to copy all of the files from
hte Hunkins project to the directory where Csound was located, as
running this from the Hunkins directory wouldn't allow GDB to find the
source files.
