Subject: 2.3.2 base class initializer bug
Organization: GNUs Not Usenet
Distribution: gnu
Date: Wed, 16 Dec 1992 02:18:15 GMT

In deriving a class from ostream in libg++-2.3, the argument to the
base class ios (a parent of ostream) is incorrectly passed.  That is,
the ostream constructor is called with a non-NULL pointer as its first
argument; it, in turn, sends its arguments to an ios constructor which
sees its first argument as NULL.

The version 2.3.2 of g++ has been patched by a patch from Michael N.
Lipp, initially submitted for version 2.2.2, that avoids a compiler
infinite loop that occurs (both in 2.2.2 and unpatched 2.3.2) when
compiling the source to his rpc++ library.  The machine and os are a
sparc and sunos4.1.2, respectively.

Here is a sample session with gdb that evokes the bug:

In the source to come, defining the preprocessor variable BUG invokes
the bug; failing to do so circumvents the bug.  The verbose compiler
output generated on this source is:
