I'm not sure but I think there may be a problem with the recent
patch to allow for PREV(vname).

/* WARNING: if new operators are added, they MUST be added after OP_END.
 * This is because COMPUTE (CDEF) DS store OP nodes by number (name is not
 * an option due to limited par array size). OP nodes must have the same
 * numeric values, otherwise the stored numbers will mean something different. */

The OP_PREV_OTHER enumeration is added well before OP_END.

If I understand the warning correctly, all COMPUTE history becomes
invalid if any operator other than number, variable, inf and prev
are used in the RPN string.
