Memory (de)allocation ...

[Ricardo Rafael]

Hi,

      I am developing a script language compiler using Flex (C++ 
classes generated) and Bison (%pure-parser directive used), that will be 
running as a multi-threaded server process (in Win32). What should I do 
in order to avoid memory leakage?

   a) Manually write all deallocation code in every single action;

   b) Use the following Bison syntax:
         %destructor { delete $$; } program
         %destructor { if ( $$.mem ) delete $$.mem; } items rule2
         %destructor { complexCode( $1 ); delete $$; } xpto_rule
         ...

   Option b) should be the correct one, right!? In case of a syntax 
error, the right destructors are always called. Am I correct?! Or am I 
missing something.

   Any previous experience ... anyone?!


Sincerely,

RR.
