+Summary: Alloc profiler causes crash in mono-1.2.5
+
+MyProject.exe runs very well under normal circumstances (mono
+MyProject.exe). It also runs very well with the statistical profiler (mono
+--profile=default:stat MyProject.exe). It crashes, however, with the alloc
+profiler (mono --profile=default:alloc MyProject.exe). The first of two
+dumps is the actual output from the command and the second dump is from gdb.
