I still haven't solved the issue (I just keep that odd line _ = &hmm) in
the middle of the code.
But I quickly looked at the assembly generated, and there is some inlined
code from time.go:790 (!?) oddly in the middle of the call to glog.V().
The code (a wrapper around alpha-beta-prunning implementation) in more
details is below. And if I remove the "elpasedTime" line, things behave as
expected (and I can remove the `_ = &hmm` line:
func TimedAlphaBeta(board *Board, scorer ai.BatchScorer, maxDepth int,
parallelize bool, randomness float32) (
bestAction Action, bestBoard *Board, bestScore float32) {
stats := abStats{}
start := time.Now()
bestAction, bestBoard, bestScore = AlphaBeta(board, scorer, maxDepth,
parallelize, randomness, &stats)
elapsedTime := time.Since(start).Seconds()
hmm := bool(glog.V(3))
_ = &hmm
if hmm {
... logging ...
}
}
It may just be a coincidence, but I thought I would report.
