-xpg flag causes CC to drop core

Question

The following causes the SunStudio C++ compiler to drop core. Is there any known work around?
$ cat >sunbug.cpp <<EOF
int main (int argc, char **argv)
return 0;
EOF
$ CC -xpg -o /tmp/a sunbug.cpp
Segmentation Fault (core dumped)
The rest of this post is additional information about the environment that might answer why I'm the first one to complain about this.

Answer 1

I can reproduce your problem using the original release of Sun Studio 12, which is what you have.
The current patched version does not have the problem. Please download and install the current Sun Studio patches here:
[http://developers.sun.com/sunstudio/downloads/patches/]
It's generally best to install patches for all the components you use.
At a minimum, get the C, C++, and Compiler Common patches.
