+* Thu Sep 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
+- due to a very strange bug I've only seen on Solaris, ptmalloc3 is removed.
+Solaris libresolv randomly uses ptmalloc3 and system allocator and makes heap
+corruption. As internal memory management have been improved, a best fit
+allocator like ptmalloc3 is not required anymore;
 - gnuplot is upgraded to 4.4.1;
 - deadlock is fixed in signal handlers: same mutex was used in standard
 subroutines (without protected sections by sigprocmask() or pthread_sigmask())
