Any updates on this? After hearing that NetSurf was crashing I downloaded
the 2.5 release and tried it myself on my beagleboard. The first crash I
got appeared to be in exactly the same part of Tinct as shown in JMB's
crash dump.
Cheers,

Hi All,
Indeed it does... There is a build option that turns this off IIRC. I
should be back at the house the relevant machine is at in a few days, so
I'll dig it out and /finally/ put it all in SVN.
Thanks!
