Some problems I've had with Andrew PL 6:

1) "console" compiled on a Sparcstation 1 gives a bus error in a
function called by the application_Start() macro on line 202 of
runapp.c.  It runs fine on a sun 3 or an IBM RT running AOS 4.3.  (The
suns both run 4.0.3).

How does one go about debugging this?  Normally, I'd go into a
debugger and get a backtrace, to see where it died, and then look at
the source code to see if I could figure out what was wrong.  With
this dynamic loading stuff, I can't figure out how to get the debugger
to tell me what function it died in, so I can't figure out how to
start debugging it.

2) .../overhead/util/lib/tokpak.c kills the Sparcstation compiler.  It
works fine if it's compiled without optimization.

3) .../config/vax_3/system.h is missing the declaration of osi_Times
and the definition of osi_GetSecs().

4) .../ams/demo/gendemo doesn't work if you don't set ANDREWDIR and
you don't build andrew in /usr/andrew.

5) .../overhead/class/testing/Imakefile should set MAKEDOFLAGS to
-b ../cmd -g -d $(BASEDIR)/lib .  Otherwise, it doesn't work if you're
not installing in /usr/andrew.

6) .../overhead/snap2/guardian/cmd/Imakefile and
.../overhead/snap2/pcserver/Imakefile refer to
${AFSBASEDIR}/lib/librauth.a, which is not part of AFS 3.0.  Things
seem to work fine if that library is removed from the compile
line--evidently AFS 3.0 has the necessary functions from that library,
but has moved them to some other library.

7) .../overhead/wpi/wpi.c , line 503, calls puts(WPI_Value("Fwd", entry));
however, if somebody has no forward field, WPI_Value returns NULL,
which makes puts() core dump.  wpi should probably check for this case
explicitly and print out something like "no forwarding address".

8) Is the AFS monitoring for console supposed to work under AFS 3.0?
The sample consoles that claim to monitor the file system always claim
"There has been no file system activity."

I'd appreciate any help with fixing the problems with console (numbers
1 and 8); the rest I've fixed myself.

Thanks,
