256 children per process is a bit tight in some scenarios. Fix this by revamping the `procs' array. Convert it to an extensible class child_procs and rename procs to chld_procs. Fix code throughout to use matching class methods rather than direct access. To allow a lot more child processes while trying to avoid allocations at DLL startup, maintain two arrays within class child_procs, one using a default size for 255 (i686) or 1023 (x86_64) children, the other, dynamically allocated on overflowing the first array, giving room for another 1023 (i686) or 4095 (x86_64) processes. On testing with a simple reproducer on a x86_64 machine with 4 Gigs RAM, a system memory overflow occured after forking about 1450 child processes, so this simple dynamic should suffice for a while.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
