Subject: libm problems on AlphaStation 4/233 (21064/Avanti)

    I just installed SuSE 6.4/AXP on an AlphaStation 4/233 (Avanti
    board). Unfortunately, there seem to be some fpu-related problems.
    Whenever a process calls floor(), it freezes.
    This can be traced back to some assembler calls in
    /usr/include/bits/mathinline.h:133. For example:

    #include <stdio.h>
    #include <math.h>

    int main() {
      double d;

      d = 1.1;

      /* This freezes on the Alpha 21064: /*
      d = floor(d);

      printf("%f\n", d);
      printf("Done!\n");
    }

    Another example is GNU awk, which makes the system almost unusable in its
    present state. Are there any known workarounds?

    Best regards,
    Markus Lischka
