------- Comment #30 from dominiq at lps dot ens dot fr 2009-01-18 13:13 -------
If I compile the test in comment #27 with -O1 and all the other flags supposed
to be turned on by -O2
(taken from
http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#Optimize-Options) the
bug does not show up. What are the missing differences between -O1 and -O2?
