Description of problem:
Attempts to call math functions from gdb produce invalid results. For
example:

(gdb) print exp(-1.23)
$2 = 1

I can reproduce the problem on older Red Hat systems as well (e.g., RH
7.3).


Version-Release number of selected component (if applicable):
gdb-6.0post-0.20040223.19

How reproducible:
Always

Steps to Reproduce:
1. Create a test program

(a.c follows)
#include <stdio.h>
#include <math.h>

int main() {
  double x;

  x = exp(-1.23);
  printf("exp(-1.23) is %f\n", x);
}

2. Compile / link

gcc -g -lm -o a a.c

3. Run test
    
gdb a
(gdb) tbreak a.c:8
Breakpoint 1 at 0x80483ff: file a.c, line 8.
(gdb) run
main () at a.c:8
(gdb) print x
$1 = 0.29229257768085942
(gdb) print exp(-1.23)
$2 = 1
(gdb) print/f exp(-1.23)
$3 = 1.40129846e-45
(gdb) print x
$4 = 0.29229257768085942
(gdb) set x=exp(-1.24)
(gdb) print x
$5 = 1
(gdb) set variable x = exp(-1.24)
(gdb) print x
$6 = 1
(gdb) p/f x
$7 = 1
(gdb) print x=exp(-1.23)
$8 = 1
(gdb) whatis x
type = double
(gdb) 


Actual Results:  See above.

Expected Results:  Value from print and assignment should have been
similar to that printed for the value of "x".
