Yes, this is definitely a problem; this should not be happening. The good news is if we can track it down, its probably possible to fix it one way or another. > In addition to speed and size differences, I have noticed that > the results returned by the software are slightly different in > the different GCC versions. Is it possible that mathematical > functions do not handle floats/doubles correctly? This is possible. GCC, particularly on MinGW, is particularly sensitive to algorithms that have stability problems. This is a problem in general on i386 due to the way that relatively simple operations (such as assignment) can cause the fp size to change. This is a very difficult problem to solve, and is present in most compilers based on i386 chips. The best workaround is careful coding to avoid inadvertent sensitivity or instability. > I will try to find some time during the weekend to generate a > minimal example that reproduces the problem. Please let me know how this goes for you. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
