possible patch

Let x.conf be a file

   x = kernel.all.uptime - proc.psinfo.start_time

Let the command to run be

   env PCP_DERIVED_CONFIG=/path/to/x.conf pminfo -f x

Observe output

  x
    value 1008990.98
    value 1008990.98
    value 1008990.97
    value 1008990.97
    value 1008990.97
    value 1008990.97
    [...]

Observe absence of instances.  Let the next command to run be

   env PCP_DERIVED_CONFIG=/path/to/x.conf pminfo -d x

Observe output:
  x
    Data Type: double  InDom: PM_INDOM_NULL 0xffffffff
    Semantics: instant  Units: sec

Observe mismatch: InDom should have been the indom of the right operand (proc.psinfo.start_time).

Examine libpcp/src/derive.c, find bugs.
