Is this a compiler error?
This program worked OK on libc5 and for a while on libc6. However, it
does not now. It segfaults every time. Unfortunately, this is happening
before any of my code gets run and I can't work out what is happening.
Here is the link command:

g++ addrform.o db.o dbwindow.o funcform.o main.o listpair.o indform.o
moneyform.o orgform.o subform.o dstring.o combo.o listitem.o listbox.o
printdlg.o printdlgData.o mdbwindow.o mlistpair.o mcombo.o mlistbox.o
maddrform.o mdbform.o mfuncform.o mindform.o mmoneyform.o morgform.o
msubform.o mprintdlg.o mprintdlgData.o -o prdb -L/usr/X11R6/lib
-L/usr/lib/postgresql/lib -shared -lqt -lpq++ -lpq -L/usr/X11R6/lib -lX11
-lpub -lcrypt -lc

This is the gdb output (I don't understand where the missing pathnames
are coming from):

and this is the shared library information:

(why did that not work, while the next command did? it is the same executable)

Is this a problem caused by mixing libraries compiled with gcc and g++?
How can I find out which library is causing the problem?

"But where shall wisdom be found? And where is the
place of understanding? It cannot be gotten for gold,
neither shall silver be weighed for the price thereof.
Whence then cometh wisdom? and where is the place of
understanding? ...Behold the fear of the Lord, that is
wisdom; and to depart from evil is understanding."
