-Recent versions of gcc have had a bug in how they emit debugging
-information for C++ methods (when using dbx-style stabs).
-This patch should fix the problem. Fix you can't fix gcc,
-you can alternatively define GCC_MANGLE_BUG when compling gdb/symtab.c.
+In the 2.3.2 release of gcc/g++, how the compiler handles resolving
+multiple inheritance lattices was reworked to properly discover
+ambiguities. We recently found an example which causes this new
+algorithm to fail in a very subtle way. For the time being, this
+patch will make the compiler use the old algorithm, which works for
+the failing case we've found. Note it will revert the compiler's
+ability to properly deduce MI ambiguities in many cases (to its state
+in 2.2.2 and 2.3.1). This bug will be fixed in the next gcc/g++
+release.
