Hi!
I think I have encountered a bug in this compiler from CXX64T01.tar:
Compaq C++ T6.4-001 for Digital UNIX V5.0 (Rev. 910)
Compiler Driver T6.4-001 (cxx) cxx Driver
I thought this was the latest cxx compiler from Compaq, but now I am not so
sure, since I see that for version 6.32 there are newer tar files available
as for this 6.4 version !? Which one should I be using? Is T6.4-001 a beta
test version? If so, where to report bugs?
The bug is as follows: Use the .cc file found below and compile it using
cxx -fast -O4 -tune host -assume noaccuracy_sensitive -MD \
-nopure_cname -noimplicit_include test.cc
The output of the program should be "7.7", but if compiled as shown above,
it is "NaNQ". The correct result of 7.7 is obtained when using -O3 instead
of -O4, or when removing the comment signs before the one "clog <<"
statement as seen in the source, or when using cxx V6.3-001 instead.
Kind Regards,
Tobias Ernst.
