+- regression introduced bt 4.0.19 is fixed in signal management.
+Interruption1() can be called from itself and raises bus error (on sparc) or
+segmentation fault;
+- sqlite is upgraded to 3.7.4;
+- OpenSSL is upgraded to 1.0.0c;
+- syntax error is correctly checked ( (2+,0) does not crash RPL/2 anymore);
+- characters are tested in recherche_type() to avoid names like '12+';

+* 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())
