The following page suggests that the problem is relatively specific to pow(): http://www.vinc17.org/research/extended.en.html (That page is cited in a context similar to ours at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16122) For now, anyway, I don't have a better solution than resetting the FP mode back to extended precision before calling pow() under Linux. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
