Sure there is still the risk that something breaks due to this problem but then this is a bug in the compiler and Intel would sure be happy about a decent bug report. > Thirdly, for the user that wants to use a program available in source only, > do > they have to install the compiler based upon the distribution?

Cleaning up and tuning the code of applications is definitely the more promissing way than just blindly replacing the compiler.
