So it is trying to set some boolean preference to true, but the
rsrcDescrip pointer is bad.

Can you run it under the debugger again? If you can find how to set
breakpoints in the debugger, you could set one at prefFile.c:329 (the
gdb syntax would be "br prefFile.c:329" ) and you can list all the
boolean preferences as it sets them. If not just run it and wait for the
crash. Display these values:

p *rsrcDescrip

Example output from gdb:
(gdb) p *rsrcDescrip
$3 = {name = 0x812d959 "autoSave", class = 0x812d950 "AutoSave",
dataType = 1, defaultString = 0x812cb11 "True", valueAddr = 0x8178334,
arg = 0x0, save = 1}

So HPUX's debugger isn't as helpful as gdb. Example output from gdb.

Maybe. I have an HPUX 10.something box with the HP compiler but without
having an exact copy of your source tree and preference files it
wouldn't be possible to replicate the problem.
