Thank you for your lenghtly respons to my request for information about
implementations of (C++) exceptions. I regard the information from David
Chase very useable (but hard to understand since I have no experience with
Sun systems and development tools).


Unfortunately I have not yet had the pleasure of trying SunPro C++ 4.0,
but in IBM PC C++ compilers as Borland C++ and Watcom exceptions means a
lot of overhead including calls of init_except_block / exit_except_black
functions for each C++ function compiled with exceptions enabled etc.


This clearly does not compute with statements from Bjarne S. and others
that exceptions should introduce no/very little overhead in a normal
running program (as long as no exceptions are thrown)!


If you know more about this subject please mail me at mmc@imada.ou.dk


Your information will be used for my graduation work for the university in
Odense, Denmark and notice of the result of the study will be posted at
comp.compilers (and mailed to you if you should request so).
