Running on Debian Linux/AMD64, NVIDIA GeForce 6800GT
I encountered two crashes in this build. First seems to be a mistake in
the mouse handling code.
The following block of code appears starting at lines 651, 730, 812 and
857 of libs/csutil/csinput.cpp and would appear to be a cut-and-paste
error:
uint32 buttonMask = 0;
for (int i=31 ; i>=0 ; i--) {
buttonMask <<= 1;
if (Button[number-1][i])
buttonMask |= 0x1;
}
Notice the Button[number-1]. Obviously this fails horribly if number ==
0, which is exactly what happened to me when I tried to run walktest.
The fix seems to be to simply remove the "-1" so that it is just
Button[number], but I'm not 100% sure of the intended behavior.
Possibly related to this is the fact that the mouse handling code in
walktest seems to be broken as well. For example, clicking the right
mouse button causes the viewpoint to start moving forward, but the "button
up" event not honored (or not noticed) so the viewpoint continues to move
forward forever and ever, and no clicking of any other mouse button has
any effect. Anyone seen this?
The second crash appears to be a somewhat naughty linking error. It seems
to be that libwx_base defines a symbol regfree(), and that this is
overriding the instance of regfree() in libc...? Anyone have any ideas?
