I obtained g++ from http://aixpdslib.seas.ucla.edu/, first tried this with
3.3.2 (which, on Sun, accepted all the same sources).  Got a core with error
similar to:
 
0xd3191688 in std::string::assign (this=<incomplete type>, __str=<incomplete
type>)
and the stack trace stops at the entry into the std::string
 
The document at
http://www-128.ibm.com/developerworks/eserver/articles/gnu.html said that I
needed to be on 3.4 or later to pass structures by value so upgraded to
4.0.0.  And got the same problems (as well has having to add a lot of this->
inside of templates).
 
Tracked this down to an assignment to a std::string subclass that was a
global that was being assigned a value.  Replace them with const char *x =
null, and got past them.  But I also have an object which is a
specialization of std::list.  When it first is accessed, empty returns
false, and clear and size enter an indeterminate loop.
 
compile options are:
g++ -g -fno-for-scope  -D_THREAD_SAFE
link options are:
g++  -Xlinker -bloadmap:loadmap -g -Xlinker -brtl -Xlinker -bminimal-toc
-L/usr/lib/threads
 
This file is actually processed twice by g++, once with -E, and this output
passed to Oracle's ProC, that output is processed again by g++.
