You're not calling regfree() between the first and second calls to
regcomp(). Here's a patch:

--- regcompleak.cpp.orig        2003-10-22 19:01:32.000000000 +0100
+++ regcompleak.cpp     2003-10-22 19:03:46.000000000 +0100
@@ -14,6 +14,10 @@
   {
     reg = new regex_t;
   }
+  else
+  {
+    regfree(reg);
+  }

   if(int err = regcomp(reg, "^[0-9]+:[A-Za-z,]+:.*$", 0))
   cleanup(err);

Cheers,
