Rui in basic_ostream

Question

Hi,
I�m using Sun Studio 12 (CC �V output CC: Sun C++ 5.9 SunOS_sparc 2007/05/03) and get an rui error using dbx.
Am I doing something wrong? Here is a test case:
$ cat testa.cc
#include <iostream>
#include <iomanip>
int main(int argc, char *argv[])
  std::cout << std::setw(4) << 23;
  return 0;
$ CC -g testa.cc
$ dbx -C a.out
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.6' in your .dbxrc

You're doing everything right; most probably, it is minor dbx issue and I think it is safe for you to ignore this problem.
If you type 'suppress -d' in dbx you should see a line like this:
(dbx) suppress -d
aib air rui - /usr/lib/libCstd.so.1
...which means that all rui type of errors in libCstd should be suppressed. Apparently, they aren't.
It would help a lot if you report this issue through bugs.sun.com (refer to this site if you have questions as to how to do that: http://wikis.sun.com/display/SunStudio/Sun+Studio+FAQ#SunStudioFAQ-GeneralHowdoIreportabuginSunStudio)
