Hi,
I've just now repeated the test again with my i586, compiled with 'gcc -O3
testbug.c -o testbug' , gcc 3.0.3 and the result is:
Results of no bugy routine 1780
Results of bugy routine 238611074
And I remember to have the same problems since gcc 3.0. On a pentium III the
problems are the same.
Guillermo.
