Description of problem:
Uninitialized local variable 'c' is used in math/test-tgmath.c.
TYPE a, b, c;
long int j;
long long int k;
a = cos (cos (x));
b = acos (acos (a));
a = sin (sin (x));
b = asin (asin (a));
a = tan (tan (x));
b = atan (atan (a));
c = atan2 (atan2 (a, c), atan2 (b, x)); ### 'c' read before written
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Actual Results: At line 176, local variable 'c' is read and used as an actual
argument to atan2() before 'c' has a value.
Expected Results: No use of uninitialized local variables.
