Re: [brlcad-users] Illegal Instruction problem in BRL-CAD 7.12.6

[Christopher S. M. <br...@ma...>]

Simon,

As you're obviously aware having read the list, you're not the first  
to run into this Illegal instruction problem.  At this point, there's  
not much left to try other than someone capable reproducing the  
problem and running in a debugger until the issue is identified.

The only other idea to try that comes to mind is to test a different  
version of the compiler (gcc 4.0 or 3.3) or a different compiler  
altogether (intel).  Similarly, trying previous (source) releases of  
BRL-CAD to see if a problem was introduced in a particular release  
would help.

Cheers!
Sean
