On more testing, I found that after having uninstalled my SVN HEAD 
build and installed the 2.0.3 package, both versions now crash with 
the Lola file. Details underneath my name if needed, but it seems odd
given both builds should be using the same system "libsbsms10 2.0.1-1". 

Are you on 32-bit Debian, Steve? 

Yes, I would guess Clayton should release/push 2.1.0 (fixed), and
perhaps we should release note the workaround to build Audacity
with the sbsms version in SVN.  

* What version of sbsms is in SVN? The audacity-patches.txt says "??"  
   for version number. Is that version the same as:
   http://sourceforge.net/projects/sbsms/files/sbsms/2.0.1/ ?

I uninstalled my HEAD build of 2.0.6-alpha and installed the 2.0.3
package version of Audacity on Ubuntu 13.10 32-bit. I tried the
"Lola" demonstration file in 2.0.3 at Initial and Final Tempo 30%
and it crashed every time as long as I selected the whole track. 

Those Initial and Final settings were the same as I had tried in HEAD 
with no 2.0.3 installed, without provoking a crash. 

But now when I try HEAD (without reinstalling it) after the package
version of 2.0.3, 2.0.6-alpha also crashes every time on the whole 
track at Initial and Final 30% and also at Initial -30 %, Final 30%. 

Neither Audacity version crashes with a selection of zero to 2 mins
32.344 seconds.
