I am experiencing a strange Coot crash issue on some of my Linux workstations. Coot 0.5.2 or 0.6-pre1 crashes with an identical failure mode with the following Coot output (last few lines):

I can run Coot 0.5.2 or 0.6-pre1 with no issues on my Q9300 quad-core machine, but on any of my Pentium 4 workstations I get this crash on startup. Coot 0.5.0 runs fine on the Pentium 4's, so it's an issue that developed with 0.5.2 and later. I'm a bit mystified.



Hello Roger,

I have not seen this before. I don't recall changing anything in this area.

As a work-around you can comment out tips.scm in xxx/share/coot/scheme/coot.scm

That might do the trick.

or add to your ~/.coot file
(no-coot-tips)


To give details in the crash report please turn on core dumping before running coot.
