#define NdrMarshSCtxtHdl(pc,p,rd)   (NdrSContextMarshall((NDR_SCONTEXT)pc,p, (NDR_RUNDOWN)rd)

由于上两段代码括号并不平衡，所以在匹配时出现超时。

正则表达式由程序生成

(\#define\s+)
  (?'Name'([a-zA-Z_]\w+))
  (?'Params'(\([^\(\)\#]*\)))?
   \s+
  ((0(x|X)[0-9a-fA-F]+)|
  (\d+)|
  ([a-zA-Z_]\w+)|
  ("(?>[^"]+|"")*")|
  (\(([^\(\)\#]+|
  (?'Paren'\()|(?'Close-Paren'\)))*?(?(Paren)(?!))\))|
  (\+|\-|\*|/\\)|
  (([a-zA-Z_]\w+)(\(([^\(\)\#]+|(?'Paren'\()|(?'Close-Paren'\)))*?(?(Paren)(?!))\))))?

简化为这两种情况之后还是出现超时
(\#define\s+)
 (?'Name'([a-zA-Z_]\w+))
  (?'Params'(\([^\(\)\#]*\)))?
   \s+
  (\(([^\(\)\#]+|(?'Paren'\()|(?'Close-Paren'\)))*?(?(Paren)(?!))\))

(\#define\s+)
   (?'Name'([a-zA-Z_]\w+))
     (.+?)
     (\(([^\(\)\#]+|(?'Paren'\()|(?'Close-Paren'\)))*?(?(Paren)(?!))\))

一些匹配和文本导致超时的情况
