Hi,

I am posting to this list as I suppose that people interested in IA64 are not that far from being interested in OpenMP stuff, and I did not find any other suse list somehow specific on this issue.

I don't know why the ia64 list would be appropriate for ia32 stuff, even if there is a similar problem with thread stacks on both linux-ia32 and linux-ia64.

The issue ist the following: we try to run the intel compiler 6.0 on a Pentium4 with Suse7.3 and 2.4.18 kernel. When switching over to OpenMP, we get segfaults in the startup phase. The intel guys told us that we would need a glibc with FLOATING_STACKS enabled, and gave us a version. However just replacing the lib leads to a complete crash of all other tools. Was this a binary version of glibc? Was it built for redhat?

So I suppose the issue is more complex. Do you have any suggestion (at least the RTFM thing -- where I can find out more) ? Could the problem be resolved by compiling glibc by ourselves ? Possibly so, if you have a recent version, and sufficient instructions. I'd certainly like to know about this. Unfortunately, I believe that OpenMP with the Intel compiler remains in a developmental state, insufficient to be advertised as a supported feature.
