UltraSparc IV (sun V490), SunBlade 2k and gcc 3.4.2

[Eljay Love-Jensen]

Hi,

Hard to say where things are going awry.

My recommendation is to compile with the -g flag (and your normal 
optimization flags, like -O2 or whatever), and when the C code fails take a 
look at the core dump's bt (backtrace) in the debugger.

Or attach the debugger to the live, running program.

Or to run the program within the debugger (if possible).

I found three compiler related optimization bugs for GCC 2.95 on an Ultra 
5, running on SunOS 5.8.  So it's not inconceivable that there may be a 
USIV related bug with GCC 3.4.2.  Maybe.  (I'm not ruling out programmer 
error, either.)

HTH,
