Sun C++ 5.6 is not a very old compiler, so I'd be surprised if it had such a fundamental bug. Are you sure you're not compiling in "compatibility mode" (e.g. -compat), http://docs.sun.com/source/819-3689/Ch2.Compat.html, which appears to allow such conversions?
5.8 is pretty old given that the latest version is 10. Even 7 isn't fully compliant. In fact I had so many problems with solaris compiler that I moved to gnu.
The latest version of the Sun C++ compiler is 5.8 - it ships with Sun Studio 11: http://developers.sun.com/prodtech/c...CCcompare.html
Positive... I compiled this test program as follows...Quote:

According to the man pages the default is -compat=5, and in fact, -compat[=4] is not supported if you use -xarch=v9!!!
And what was the exact text (e.g. copied and pasted) of the program?
Post #15 has the code I was curious/concerned about. But here is another variant with some output statements thrown in.Quote:

*&c = A
*&c = B
That's a pretty shocking bug - if you're in the mood, you could do Sun a favour and report it, though it might have been fixed in 5.7 or 5.8.
