I've built Sage 64-bit on OpenSolaris but it crashes at startup. I've

allows Sage to run. It's not 100% stable, but much better than before.

Can anyone see if there might be something wrong with this code,
which is causing Sage to segfault?
It might be due to the linker initializing the library in a different
order. Can you post a backtrace so we can see which function it is
trying to construct?
Here's a backtrace
