I have made a simuation program with sparse matrix routines. One funny
things with g++ 2.91.66
is that an executable without optimization flag ( -g or no-flag) ran
well; however, the executable
with optimization flag (-O, -O2, -O3) caused errors after 5 iterations.
My linux is on:
Intel Pentium2 400MHz
128 M SDRAM
Debian 2.1 Slink
g++.2.91.66
libstd++2.9
Unfortunately, my source files are bigger that 1M byte.
How can send my source files ?.
