-Here are _all_ the issues that have been raised vis-a-vis the 5.0

+Known problems in GDB 5.0
+=========================
 
-If, however, you fix something, then feel free to tweek this file
-(deleting the problem).  Just send a note to gdb-patches so that I see
-the change.
+Below is a list of problems identified during the GDB 5.0 release
+cycle.  People hope to have these problems fixed in a follow-on
+release.

-Generic: lin-thread cannot handle thread exit (Mark Kettenis, Michael Snyder)

+Generic: lin-thread cannot handle thread exit (Mark Kettenis, Michael

 The thread_db assisted debugging code doesn't handle exiting threads
 properly, at least in combination with glibc 2.1.3 (the framework is
 there, just not the actual code).  There are at least two problems
 that prevent this from working.

-problems loading shared libraries - with attached test case

-Hi, I'm having problems loading shared libraries.  This is with a
-build of gdb out of cvs that I pulled and built on March 27th and has
-been there for at least a week.  I haven't gone back further than
-that.  This is with the gcc that is shipping with Red Hat 6.2:

-Reading specs from
-/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs gcc version
-egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
-
-I'm using "set auto-solib-add 0" after main has been called.  If I use
-"shar" to load a shared library manually once I can't use it again to
-load another shared library later.  Please see the attached log for an
-example of how to reproduce the problem.

-FreeBSD haven't contributed their local GDB changes back to the master
-sources (they would at least need an FSF assignment by all
-individuales that contributed to the work).  Given the strong
-likelhood that this will never happen, I'd suggest that a better
-strategy would be for someone (with an FSF/GDD assignment) to do a new
-(clean-room) implementation.  That can then be accepted in time for
-GDB 5.1.

-The typeinfo functions are always at offset 4 from the beginning of the vtable,
-and are always right. The vtables will have weird names like E::VB sometimes.
-The typeinfo function will always be "E type_info function", or somesuch.

-value_virtual_fn_field needs to be fixed so there are no failures for virtual
-functions for C++ using g++.
