+gdb/1091: Constructor breakpoints ignored
+gdb/1193: g++ 3.3 creates multiple constructors: gdb 5.3 can't set breakpoints
 
-*-*-freebsd*
----------------
+When gcc 3.x compiles a C++ constructor or C++ destructor, it generates
+2 or 3 different versions of the object code.  These versions have
+unique mangled names (they have to, in order for linking to work), but
+they have identical source code names, which leads to a great deal of
+confusion.  Specifically, if you set a breakpoint in a constructor or a
+destructor, gdb will put a breakpoint in one of the versions, but your
+program may execute the other version.  This makes it impossible to set
+breakpoints reliably in constructors or destructors.
 
-Due to a kernel bug (kern/35175), detaching from an attached process
-will very likely cause the process to be stop or die with a Trace/BPT
-trap.
+gcc 3.x generates these multiple object code functions in order to
+implement virtual base classes.  gcc 2.x generated just one object code
+function with a hidden parameter, but gcc 3.x conforms to a multi-vendor
+ABI for C++ which requires multiple object code functions.
 
+gdb/1322: "internal-error: sect_index_text not initialized" after printing a java type
 
-i386-*-freebsd[34]*
--------------------
+When gdb debugs a Java program which uses shared libraries, it can
+generate this internal error.
 
-There is a bug (bin/41671) in FreeBSD's gcc that causes it to emit bad
-debug information when using the stabs format (which is the default).
-As a result GDB tends to place breakpoints on functions before the
-function prologue, and information about function parameters and local
-variables is lost.  In earlier versions of GDB the effects were rather
-limited, but starting with GDB 5.3 the influence is much more
-prominent.  As a workaround, compile your code with -gdwarf-2.
+If you get this error when debugging Java, you can try working around
+the problem by relinking your program with no shared libraries at all
+(even the standard C library).  With the GNU linker, use the "-static"
+argument to do this.
 
+You can also try this patch for gdb:
 
-hppa2.0-hp-hpux10.20
---------------------
-
-gdb/487: The top level make files used to build GDB are not compatible
-with HP/UX make.  As a workaround, use GNU make.
-
-gdb/486: The HP/UX C compiler defaults to K&R mode but GDB only builds
-with an ISO C compiler.  The top level configuration incorrectly sets
-CC to `cc' instead of `cc -Ae'.  As a workaround, the correct compiler
-can be specified as part of the configuration vis:
-
-    $  'CC=cc -Ae' ./configure
-
-
-s390*-*-*
----------
-
-gdb/513: GDB does not build on s390 GNU/Linux.  The problem should be
-fixed in more recent sources.
-
-
-i386-*-freebsd4.4*
-------------------
-
-gdb/455: GDB doesn't build on a FreeBSD 4.4-STABLE system.  The
-problem is still being investigated.
-
-alpha*-*-osf*
--------------
-
-gdb/816: When building GDB with GCC 3.0.1, GDB is unable to load a core
-file properly. It generates several errors and warnings regarding
-unhandled core file section types, incorrect endianness, the failure to
-load the registers. Are also incorrectly reported: The program name, the
-cause of the program death, and the call stack at the moment of the
-death. This problem has been reported on alpha-osf4.0f and alpha-osf5.1a.
-To work-around the problem, add -D__digital__ to the CFLAGS when
-building GDB vis:
-
-    $ make CFLAGS='-O2 -D__digital__'
-
-
-i[3456]86-*-linux*
-------------------
-
-gdb/660: gdb does not build with linux libc5.  The symptom is a parse
-error before `uintptr_t'.  Upgrade to glibc 2.1.3 or later, which
-defines uintptr_t.
-
-gdb/1030: GNU binutils 2.12.1 and earlier versions do not work properly
-with gdb.  If you use GNU binutils, upgrade to version 2.13 or later.
-You can check the version of binutils with the command:
-
-    $ ld --version
