I've tried both the CodeSourcery version and 2.2.0: CodeSourcery versions: arm-none-linux-gnueabi-objdump --version; arm-none-linux-gnueabi-g++ --version; arm-none-linux-gnueabi-as --version GNU objdump (Sourcery G++ Lite 2009q3-67) 2.19.51.20090709 Copyright 2008 Free Software Foundation, Inc.

If by that you mean "copy the toolchain" - yes, the toolchains are identical (at least the CodeSourcery chains are - the newer chain is part of an ongoing, but currently stalled, project to bring the tools more up to date). > > The symptoms you describe sound like a use of uninitialised memory bug. > However we need more information (as requested above) to be able to > diagnose > the issue further. > That may be (I assume you mean "uninitialized memory bug in the assembler"), but it's odd that it is so consistently wrong on my machine and so consistently right on my coworkers.
