This is the same problem. It will fail on all 32 bit RISC platforms (which tend not to have double-word atomics, like many of the more CISCy platforms). So SPARC32, ppc32, and mips32 are all going to fail. Working on a fix, but it's going to take a bit. Brian -- Brian W. Barrett Scalable System Software Group Sandia National Laboratories
