Package: libc6
Version: 2.3.2.ds1-11
Severity: normal
*** Please type your report below this line ***
A strange but very reproducible bug (at least for me). I can only
see this bug in xine. I have xine-ui 0.9.23-2. Here's how to reproduce
it:
1) start xine
2) bring out the gui (default skin if that matters)
3) hover over any button that has a tool tip
4) move the mouse while the tool tip is still on the screen
The result is a segfault. If the mouse is moved only after the
tool tip disapears, no segfault. Using GDB the segfault seems
to occur in thread #11. The place where the error takes place
(to the best of my investigation) is
0x40430b38 in _Unwind_Find_FDE () from /lib/tls/i686/cmov/libc.so.6
I can only reproduce this bug on one of my machines (athlon, kernel
2.6.2), and only using the TLS libc6 (libc6 or libc6-i686). This
bug does not show up with libc6-dbg or any of the following
configurations: athlon, kernel 2.4.18; k6-III, kernel 2.6.1.
I'm happy to provide more debug information if needed.
Igor

OK, so I close this bug.
