Subject: bug#9990: valgrind warning in add_row_entry
Date: Tue, 08 Nov 2011 09:27:06 -0500 [thread overview]
Message-ID: <yxqwrbaadvp.fsf@fencepost.gnu.org> (raw)
valgrind ./temacs -Q gets this warning:
==7487== Use of uninitialised value of size 8
==7487== at 0x4140F4: update_window (dispnew.c:4212)

The line in question is:
4212 entry = row_table[i];
(gdb) p i
$1 = 0x157
(gdb) p row_table[i]
$2 = (struct row_entry *) 0x0
(gdb) p row_table_size
$3 = 0x193
Is it possible for the contents of row_table to be uninitialized? Is this warning a false positive?
