The about box reports 1.8.5 compiled on 3/11/07 using the latest CVS  
update.

I'm pretty sure I tried this, but I will try again the next time it  
happens. It has been running for more than 12hrs now without a  
lockup. In fact I just sent a message to a friend, a reply to a  
message he sent at 1945 last night.

Bummer. But I'd still like to fix it.

Any more advice here on how to tell which belong and which don't?

According to Fink (package management software) I have version 4.4  
installed (and no other). Looking at the libdir I have portions of at  
least versions: 3.3, 4.2, 4.3, 4.4. What should I look for in incdir?  
The only thing I see there that seems to relate is a db4 directory.  
In the db4 directory is a db.h file which lists it's version as 4.4.20.

I'm pretty sure they're finding them. I have a prefix command which  
gets them there. It's been working for over a year, so I hesitate to  
suspect this. Rather I think the db4 problem relates to periodic  
upgrades that left fragments behind that need cleaning.

Using Mac OS X here. Since I use Fink, which installs everything in  
a /sw directory, I need to use the prefix flag to tell the compiler  
where to find those fragments installed by Fink. I know DarwinPorts  
installs in the 'proper' location, but I've been using Fink for a  
long time and am happy with it's performance so why switch.

This might relate to the problem. I have Lesstif installed and have  
been using it successfully since Sept 06. If you look in the message  
archives you will see we had an exchange then (09/06) regarding a  
problem I was having which was resolved by abandoning OpenMotif and  
embracing Lesstif.

Is there something more I can do to help narrow down the cause of the  
crash? I have profiling off (because of the large files it creates)  
but I can turn it back on if it will help. I have libgc also off, but  
I'm sure I can enable it if necessary.
