According to the C++ standard (6.7) you are allowed to jump past a declaration:

"It is possible to transfer into a block, but not in a way that
bypasses declarations with initialization. A program that jumps from a
point where a local variable with automatic storage duration is not in
scope to a point where it is in scope is ill-formed unless the
variable has POD type and is declared without an initializer."

Changing it to two lines will make it work:
int j;
j = 6;

  replace int j = 6;
with
	int j;
	j = 6;
  C++ standard: not able to bypasses declaration with initialization.

I am using g++ 4.5.1 on FC14 and the below code does not compile over there.

Use 'g++ --version' to know your g++ version.
