Doeas anyboudy succesfully run kannel on x86_64? Do I need to add some flags to gcc? I'm sure that it isn't only problem with this particular processor, the same is AMD Opteron 246 processor either with or without SMP.
Get cvs version. It compiles and run on x86_64 without segfaulting.It has other problems though. Not properly handling chunked encoding posts and stopping from time to time.
