Preprocessed source of the problematic file
Hi,
as I told to the IRC, here it is the preprocessed source with the problem. The
message is reported for this code:
[code]
void DBaseStatusBar::BlendView (float blend[4])
{
V_AddBlend (BaseBlendR / 255.f, BaseBlendG / 255.f, BaseBlendB / 255.f,
BaseBlendA, blend);
V_AddPlayerBlend(CPlayer, blend, 1.0f, 228);
if (screen->Accel2D || (CPlayer->camera != NULL && menuactive == MENU_Off
&& ConsoleState == c_up))
{
player_t *player = (CPlayer->camera != NULL && CPlayer->camera->player
!= NULL) ? CPlayer->camera->player : CPlayer; // <- here
V_AddBlend (player->BlendR, player->BlendG, player->BlendB,
player->BlendA, blend);
}
V_SetBlend ((int)(blend[0] * 255.0f), (int)(blend[1] * 255.0f),
(int)(blend[2] * 255.0f), (int)(blend[3] * 256.0f));
}
[/code]</pre>
