hi. i'm running AT&T C++ 2.1 (3/19/90) on a DECStation. [ULTRIX V4.1 (Rev. 52) System #1: Tue Jan 15 15:25:58 EST 1991 UWS V4.1 (Rev. 197)] for some programs when i compile (default arguments -- i tried various levels of optimization include -O0), i get the following error at RUN TIME: Fixed up unaligned data access for pid 7468 (example4) at pc 0x406cb0 Fixed up unaligned data access for pid 7468 (example4) at pc ..... --- continues for 10 or so lines of same stuff --- some programs function properly after printing out these messages while some do not. not all programs exhibit this phenomena. i have yet to find a small program which causes this problem - so i cannot be more specific at this time. any ideas on what might be causing this, so i know where to look?? thanks. arthur butler (ajb@ee.wpi.edu)

This is output from AT&T's translator, but to pin down the application code causing it would require seeing the program. As only one machine on campus has this version of C++, you'll probably have to consult the AT&T C++ manuals in CCC or Usenet (comp.lang.c++). -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Peter Fay College Computing Center ~ ~ (fay@wpi.wpi.edu) Worcester Polytechnic Institute ~ ~ (508)831-5725 100 Institute Road ~ ~ Worcester, MA 01609 ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
