Summary0031529: Build Windows: Scripts with multiple argument variables in an assignment can generate a warning during YYC builds
DescriptionIssue:
 When building a project for YYC that contains scripts that have multiple references to argument variables will generate "YYError("referencing argument index out of range %d"" errors, such as:

Z:/yycwarning_77216A98/yycwarning/default/Scripts/llvm-win/gml_Script_drawcrosshair.gml.cpp:31:20: warning: multiple unsequenced modifications to '_yytmp_' [-Wunsequenced]
local_len=((*_args[YY_CHECK_ARG_RANGE((int)(0), _count)]) + (((*_args[YY_CHECK_ARG_RANGE((int)(0), _count)]) * 0.5) * (/* local */local_dis / (double)16)));
                   ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
X://yyc/include\YYGML.h:70:44: note: expanded from macro 'YY_CHECK_ARG_RANGE'
#define YY_CHECK_ARG_RANGE( i, r ) (_yytmp_=(i), ((_yytmp_<(r)) ? _yytmp_ : (YYError("referencing argument index out of range %d", _yytmp_), 0)))

This does not prevent the build, nor is any unusual behaviour seen in game.


Example for clarification:

//this does not generate any warnings
var arg0 = argument[0];
var len = arg0 + (arg0*0.5);

//this generates warnings
//var len = argument[0] + (argument[0]*0.5);
Steps To Reproduce1. import attached project
2. select windows yyc as target platform
3. run project
4. observe an error like shown in the description is generated in the output window
