I tried to use the trunk of the poolalloc svn repository with the llvm 2.7 release which is working fine for most of the programs I ran it on so far but for sqlite it's running into a stack overflow since it is endlessly looping in the BUDataStructure::calculateGraphs method (excerpt of the debugging output is attached).
Yep, I'm familiar with the error. Does this still happen after the
commits from last night?

I just wanted to send this for case this behavior is not expected and to ask if there is a revision for which the BU DSA is known to work at least stable in most cases such that I can work with llvm 2.7. Or is there any plan on when a stable version for 2.7 (or even better 2.8) will be available?
Thanks for understanding that it's a work-in-progress, and appreciate
the report. I don't believe there's a stable revision for 2.7, that's
what we're working for presently :).
If you'd like, feel free to send me the bitcode file and I can try to
prioritize fixing the issue you're seeing if it's not fixed already.
Alternatively consider filing a bugreport, both DSA and poolalloc have
projects on the bug tracker (http://llvm.org/bugs), so we can take
care of it... and again an example demonstrating your issue is
appreciated if possible.
Hope this helps,
