[Buildroot] Building x86_64 Toolchain

[Jonathan Haws]

I am having some issues building the initial toolchain for an x86_64 target.  It gets to a point when it is building GCC and I get a segmentation fault.  The error is pasted below.

I tried this with all versions of GCC available, the stable release of Buildroot, as well as the latest snapshot of Buildroot.  I get the exact same errors regardless of which GCC or version of Buildroot.  However, I get two different errors based on the version of linuxthreads I include.

I am not sure what to make of either one.  Can anyone point me in the right direction?  My host system is running Fedora 12, 2.6.32.26, GCC 4.4.4, BinUtils 2.19.

Thanks!

Jonathan
