While vmalloc's debugging is less of a performance hit than some other implementations of memory allocation debugging, performance is probably less of a concern than correctness when debugging (and the specific line of code that you referenced is only executed when debugging mode is activated). You might want to lower the -O level or disable the strict aliasing "feature" for the specific file in question. _______________________________________________ ast-developers mailing list [email protected] https://mailman.research.att.com/mailman/listinfo/ast-developers
