You shouldn't panic when you find one. The -O2 option is definitely usable. Entire linux distributions have been built with it. There are some known problems with the C++ support in the 000216 release. There was a lot of C++ front end development work happening at the time, and we ended up with an FSF gcc snapshot that has a few instabilities in the C++ front end. Otherwise, the release has held up very well. There haven't been very many problems with it. Bug reports sent here are OK. Bug reports sent to the usual FSF addresses are OK, if you make it clear that you are using one of the unofficial releases that the ia64-linux project is using. There is a new toolchain release that you can try if you are interested. I expect that the next series of linux distributions will use this new toolchain. It is located on ftp.cygnus.com in pub/ia64-linux. I am not too interested in bug reports against the old toolchain at this point, but I will help if I can. Jim
