Unfortunately I don't have that platform to test on... and since we don't have a regular test-runner testing that platform either (care to volunteer?) I'm afraid I wasn't aware it was broken. It does build for me on Linux with sun's compiler though.

Thanks a lot for the quick reply. I've done builds of Boost 1.46.1 with versions 5.10 and 5.11 of Sun's compiler. The relevant output is attached. The failures are the same with both versions of the compiler. Just to recap, this is a 32-bit x86 box running Solaris 10. The builds were done with the following characteristics: static linking, multi-threading, release variant.

To summarize: Sun's compiler hates the file regex_primitives.hpp. (Come to think of it, that's not even from the regex library, is it?) I apologize for blaming the regex library. It appears that the graph library is the problem.

Thanks,
Will
