Description

gcc -c -m32 s.28143037.2.s.c
s.28143037.2.s.c: In function ‘func_1_slice_1’:
s.28143037.2.s.c:118: error: ‘tmp_17’ undeclared (first use in this function)
s.28143037.2.s.c:118: error: (Each undeclared identifier is reported only once

Notes
(0001821) Anne (reporter) 2011-04-28 14:42	I am sure that you keep on some slicing bugs in reserve to be always ready to feed the BTS, don't you ? ;-) I'll have a look...

(0001822) pascal (reporter) 2011-04-28 14:53	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.

(0001823) Anne (reporter) 2011-04-28 15:00	Again a bug in [filter] while building the new project !

(0001824) Anne (reporter) 2011-04-28 16:08	The problem was that when building a block with only one statement, the block was droped even if it declared local variables.
