Before the mentioned commit the "Too many vertex shader uniform
components" message wasn't present. You can see how the error looked before in
bug 42514.
Concerning the breakpoint I had some troubles with wine debugging so I had to
use an glretrace to obtain it, I hope this isn't a problem.
Breakpoint 1, check_resources (ctx=0x8404fd8, prog=0x8431478)
at linker.cpp:1913
1913 shader_names[i]);
Missing separate debuginfos, use: debuginfo-install
libXdamage-1.1.3-2.fc15.i686 libdrm-2.4.26-3.fc16.i686
libffi-3.0.10-1.fc16.i686 libtxc_dxtn-1.0.0-1.fc15.i686
(gdb) print sh->num_uniform_components
$1 = 3936
(gdb) print max_uniform_components[i]
$2 = 1024
