This bug was introduced +by a new feature in glibc. +* Thu Apr 14 2011 BERTRAND Joël rpl-4.0.22 (RPL/2) +- by default, RPL/2 uses "NONE" IMPLICIT when it's started in batch mode and +"ALL" IMPLICIT when it runs in interactive mode; +- when "NONE" IMPLICIT is set, STO intrinsic raises an error when it is used +to create or modify a global variable. Now, with "NONE" IMPLICIT, you have +to use SAVE to manipulate global variables; +- replace erroneous TAB by TBL in evaluation() and formateur_fichier() +subroutines; +- fix major memory access violation in evaluation subroutine. Only occurs +when 'X(i,j)' is evaluated on a matrix and when (i,j) points out of bounds; +- fix major bug in evaluation subroutine.

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()) +and signal handlers. A new signal handler specific mutex is added; +- minor bug is fixed in evaluation() subroutine. In { X 0 PI }, PI is a function +that has to be evaluated by ->NUM; +- rplfile build process is modify to be sure that rplfile is not modified +after rpl build stage (to be sure that rplfile checksum is not modified after +rpl compilation); +- AWK is replaced by rplawk. rplawk is original awk written by Brian Kernighan, +modified to remove yacc code and renamed; +- some workarounds have been written to not use buggy klibc SystemV IPCS. +ABORT now works on eComStation; +- sqlite is upgraded to 3.7.2; +- bug is fixed in software interrupts. When both process have different PID, +parent process was not interrupted if it is not group master process. To fix +this bug, SIGINJECT signal is not sent by child process but by control thread +in parent process; +- minor bug is fixed in data injection (POKE) that does not work as expected +when child process is protected by NRPROC. * Thu Aug 26 2010 BERTRAND Joël rpl-4.0.18 (RPL/2) - --enable-sysv-sems is added to configure script to use SystemV semaphores functions instead of POSIX functions. This function is disabled or forced on systems that does not provide correct POSIX or SysV semaphores subsystem; - a dirty but not quick patch is written to workaround broken siginfo structures. This patch has been successfully tested. It uses a segment of -shared memory (SysV) and eleven semaphores (Posix or SysV) by process +shared memory (Posix or SysV) and some semaphores (Posix or SysV) by process (Unix PID); - some OpenBSD's hacks are added; - broken siginfo->si_pid field is now checked by configure script;
