The regular expression code in String.cc leads to a serious problem: In Regex::initialize a buffer is allocated via a call to new and the following call to re_compile_pattern may call realloc (EXTEND_BUFFER) on this buffer. This leads to problems if new is not a simple call to malloc. We reimplemented new to speed up operations on objects of the generic vector classes and use a very simple and efficient scheme for the allocation of small chunks of memory out of a internally managed pool. We achieved a speedup of about 2 this way and don't want to lose it because we use regular expressions. Question: Is there a simple way to clean up the memory management? Would it be feasible to use malloc instead of new in String.cc ?
