Summary: Early return from while() loop fails
Initial Comment:
The simple example below reproduces the problem:
route {
xlog("L_INFO", "Entering Route TEST\n");
route(R_TEST);
xlog("L_INFO", "Returning from Route TEST\n");
}
route[R_TEST] {
$var(x) = 0;
while ($var(x) < 5) {
$var(x) = $var(x) + 1;
xlog("L_INFO", "Route Test: x=$var(x)\n");
if ($var(x) == 3) {
return;
}
}
return;
}
The logs produces are:
Entering Route TEST
Route Test: x=1
Route Test: x=2
Route Test: x=3
Note the the log message indicating a return from R_TEST is NOT produced.
If the while() condition is changed so that the loop completes all of its iterations, then the message indicating a return from R_TEST IS produced.
