I'm trying to build a mono application and have came across the problem that was reported to the mono folks (mono #347359). The symptom is that gmcs hangs (30 some hours on a 50 line .CS program before I ctrl-C). The authors of the package that I was trying to build reported the problem to the mono folks and there is a fix in the svn for mono. This is not a "gentoo" bug, but a request to see if a patch can be developed. This does fail on multiple platforms, and is not gentoo specific. Reproducible: Always Steps to Reproduce: See the referenced URL for the test case. Actual Results: Excessive CPU time and utilization when compiling certain source code using gmcs I believe that patch is in mcs/.../expression.cs
Pulled a patch for this from svn. Should be fixed with -r2.
