Romulo,
you most probably compiled with gcc (the default), right. That's fine. Moreover, gcc also works fine with testing.
However, icc (the Intel compiler) is a bit more "picky" (read: *accurate*) and points out that in function create_func(), variable "sub_f" is set, but never used --- looking at the code, I must say icc is (as always) very right so:
In fucntion create_func() in sql/src/server/sql_psm.mx, variable "sub_f" is declared and initialized (set) to NULL in line 508. Then, in line 525, variable "sub_f" is set to "sql_bind_func_(s, fname, type_list)". However, there is no further occurance of variable "sub_f" in function create_func(); hence, it is set (see above) but *never* *used*...
... either you "forgot" to used (the content of) variable "sub_f" "somewhere" in function create_func(), or you don't need it. In the former case, icc helped you to find a BUG in your code. In the latter case, you should remove variable "sub_f" from function create_func(), i.e., remove line 508 and change line 525 from if (!instantiate && (sub_f = sql_bind_func_(s, fname, type_list))) { to if (!instantiate && sql_bind_func_(s, fname, type_list)) {

Maybe YOUR checkins since 28.04.2007, 04:03:41 caused some of the problems:

Summary:
- 1 New systems
!! 3 Systems now DON'T produce output !!
I compiled my sources before the commit with optimization on: --enable-strict --enable-assert --enable-optimize --enable-bits=64
Why the variable initialized, but never used is not detected by this compilation? Which compilation must be done to detect these kind of errors?
