Jakub,
Are you running a native ia64->ia64 compiler or a cross-compiler? Do you happen to know if this occurs when using a cross-compiler to ia64?

Thanks, Patrick. I'm guessing it only happens with a native compiler,
but that's just a wild guess.

Hope that helps,

A native compiler.

Do you happen to know if this occurs when using a cross-compiler to
ia64?


No, sorry.
