[COOT] Coot crash issue

[Roger Rowlett]

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):

[...]
load "tips.scm"
load "americanisms.scm"
load "group-settings.scm"
(set-display-lists-for-maps 0)
load "tips-gui.scm"
/usr/local/bin/coot-0.6-pre1/bin/coot: line 124: 14996 Illegal
instruction $coot_real $*
coot-exe: "/usr/local/bin/coot-0.6-pre1/bin/coot-real"
coot-version:
/usr/local/bin/coot-0.6-pre1/bin/coot-real
platform:
/bin/uname
core: #f
No core file found. No debugging

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.

Running Fedora 8, using Fedora 6 (0.5.X) or Fedora 8 (0.6-pre1)
binaries. "uname -a" gives:

Linux jalapeno 2.6.26.8-57.fc8 #1 SMP Thu
Dec 18 19:19:45 EST 2008 i686 i686 i386 GNU/Linux

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.
