[cl-opengl-devel] division-by-zero error

[James Baker]

(argh, forgot to cc the list!)

sorry, should have included more details in the first mail.  I'm
 running debian stable, using the closed-source nvidia drivers and
 built sbcl from source myself.

 ok well, using (sb-int:with-float-traps-masked (:invalid
 :divide-by-zero)) as suggested by Luís allows me to load
 cl-glut-examples, but the issue still occurs if i try to run an
 example (i.e. rb-hello)

 backtrace from there is =


 (SB-VM:SIGFPE-HANDLER
  #<unavailable argument>
  #.(SB-SYS:INT-SAP #XB79FB36C)
  #<unavailable argument>)
 0] backtrace
