I am sure that you keep on some slicing bugs in reserve to be always ready to feed the BTS, don't you ? ;-)

No, no, these are with the new SVN version. I launched 4 instances of my slicing testing script as soon as you closed all functional slicing bugs in the BTS. The digits are DDHHMMSS.

The problem was that when building a block with only one statement, the block was droped even if it declared local variables.
