Further to my earlier answer, 261 was exposing a double-precision arithmetic instability in the calculation of the number of samples to report in pmval ... the answer was 9 for some versions of gcc on ia32 and ia64 and all IRIX C compilers, and 8 for some versions of gcc in ia32. The attached 261 fixes this.
