While trying to upgrade to the latest version in trunk (rev. 2537), I have noticed a regression that causes a crash:

in as_compiler.cpp on line 3252 and 3262, GetTypeInfo() may return NULL and it is not check, causing a crash if you try to compile this type of code:

int j=0;

ref@ myRef=j;

So I suggest that the returned pointer is simply checked to NULL above (line 3243):

						if (lexpr.type.dataType.IsHandleToAsHandleType() && expr->type.dataType.GetTypeInfo()!=NULL) // FIXME: check that typeInfo is not NULL
						{
							useHndlAssign = true;

							// Make sure the right hand expression is treated as a handle
							if (!expr->type.isExplicitHandle && !expr->type.IsNullConstant())
							{
								// TODO: Clean-up: This code is from CompileExpressionPreOp. Create a reusable function
								// Convert the expression to a handle
								if (!expr->type.dataType.IsObjectHandle() && !(expr->type.dataType.GetTypeInfo()->flags & asOBJ_ASHANDLE))
								{
									asCDataType to = expr->type.dataType;
									to.MakeHandle(true);
									to.MakeReference(true);
									to.MakeHandleToConst(expr->type.dataType.IsReadOnly());
									ImplicitConversion(expr, to, node, asIC_IMPLICIT_CONV, true, false);

									asASSERT(expr->type.dataType.IsObjectHandle());
								}
								else if (expr->type.dataType.GetTypeInfo()->flags & asOBJ_ASHANDLE)
								{
									// For the ASHANDLE type we'll simply set the expression as a handle
									expr->type.dataType.MakeHandle(true);
								}
								expr->type.isExplicitHandle = true;
							}
						}
						assigned = CompileOverloadedDualOperator(node, &lexpr, expr, false, &ctx, useHndlAssign);

thanks!
