This release, for Linux, includes: * threads * floating point fixes * a fix regarding backtraces through signal handlers * many C++ fixes (compared with GDB 4.18) probably some other stuff I'm forgetting. For those who have been following GDB development, this is nothing new, it is the 19991004 snapshot, very lightly patched. But it my hope that putting it into an RPM package will lead to more people testing it. Get x86 and source RPM packages at http://people.redhat.com/kingdon/ Report bugs at http://developer.redhat.com/bugzilla/ (you can put in "rawhide" for the release as this package will be in the next weekly rawhide release) and/or http://sourceware.cygnus.com/gdb/ (take your pick).
