Variable is not live at this point in cuda-gdb

[lclin]

And still with CUDA 3.1 :( the variable should be in scope of the line…

Here is what it looks in gdb.

(cuda-gdb) info line

Line 94 of..

(cuda-gdb) info line

87			lambda = dotP(Cfx - ax, Cfy - ay, Sx, Sy)

88				   / dotP(bx - ax, by - ay, Sx, Sy);

89			

90			

91			// Debug check lambdas

92			// validation_data[i+20] = lambda;

93			// ---

94			

95			if (lambda <= 1 && lambda >= 0) {

(cuda-gdb) p Cfx

warning: Variable is not live at this point. Returning garbage value.

$8 = -nan(0x7fffff)

Cfx has been defined outside the loop in which line 95 is. Device has compute capability 1.3.

How to fix this problem now with cuda 4.0.
