FIFA 08 (also demo version, link in URL) crashes when starting a match (you see
some frames, and when the game is going to show players, it crashes) in Wine
1.1.31 and later (also in current git). This was introduced in this commit:

wined3d: Don't reserve clipping constants needlessly.
author    Stefan Dösinger <stefan at codeweavers.com>
     Tue, 6 Oct 2009 18:59:44 +0000 (20:59 +0200)
commit    8a68f418dbea0967003818e5bbac10e5ffc22512

I added the following code right before the new if..else clause in
dlls/wined3d/arb_program_shader.c in current git:

FIXME("clip_limit: gl_info->limits.clipplanes = %u\n",
gl_info->limits.clipplanes);
FIXME("clip_limit: ctx->target_version = %u (ARB = %d)\n", ctx->target_version,
ARB);
FIXME("clip_limit: use_nv_clip(gl_info) = %d, ctx->target_version >= NV2 =
%d\n", use_nv_clip(gl_info), ctx->target_version >= NV2);
unsigned int __mask = ctx->cur_vs_args->boolclip.clipplane_mask;
FIXME("clip_limit: mask = %u\n", __mask);
FIXME("clip_limit: count_bits(mask) = %u\n", count_bits(__mask));

And got those messages right before the crash:

fixme:d3d_shader:shader_generate_arb_declarations clip_limit:
gl_info->limits.clipplanes = 6
fixme:d3d_shader:shader_generate_arb_declarations clip_limit:
ctx->target_version = 0 (ARB = 0)
fixme:d3d_shader:shader_generate_arb_declarations clip_limit:
use_nv_clip(gl_info) = 0, ctx->target_version >= NV2 = 0
fixme:d3d_shader:shader_generate_arb_declarations clip_limit: mask = 0
fixme:d3d_shader:shader_generate_arb_declarations clip_limit: count_bits(mask)
= 0

And by the way I've also tried adding the following code in place of this
if..else clause in the current git:
clip_limit = gl_info->limits.clipplanes;
if(ctx->target_version == ARB) clip_limit = min(clip_limit, 4);
And FIFA doesn't crash then, but I guess it's not the proper way to fix the
problem.
