+Summary: Built runtime gives SEGV inside GC code on Solaris/SPARC
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+mono runtime binary (./mono/mini/mono) dies with a SEGV inside the garbage
+collection initialisation code.
+
+Steps to reproduce the problem:
+1. ./configure
+2. make
+3. (since the build process relies on the runtime for building the class
+    library, the build process terminates as soon as the runtime is used)
+
+How often does this happen? 
+Everytime the runtime needs to initialise the GC (calling ./mono/mini/mono
+without parameters gives the usage message)
+
+Additional Information:
+
+stack trace (from dbx)
