December 02, 2003 Bug: 'variable used before set' error | ||||
---|---|---|---|---|
| ||||
typedef struct AB { int a; int b; } AB; void func(AB *pAB, int count) { AB temp; for (count--; count>=0; count--) { temp = pAB[ count ]; temp.a /= 2; /* (A) */ temp.b /= 2; /* (B) */ pAB[ count ] = temp; } } --- The code listed above gives a "Warning 12: variable 'struct AB temp' used before set" when compiled with the -o+speed switch. The compiler does not generate correct code for line (A); temp.a contains unknown data. No problems with line (B). It seems that only the first member of a structure is 'ignored'. |
