+Description of Problem:
+During extensive use of System.Reflection.Emit API the method for fetching
+fields fails.
+
+Steps to reproduce the problem:
+1. Download Nemerle snapshot
+http://nemerle.org/download/snapshots/nemerle-0.9.3.99.7754.tar.gz
+2. Do  ./configure
+3. make
+
+Actual Results:
+make[3]: Entering directory `/home/users/nemweb/nemerle-0.9.3.99.7754/ncc'
+COMPILE [stage1] Nemerle.dll
+___________.................................................

+
+Expected Results:
+Should compile cleanly
+
+How often does this happen? 
+Always
+
+Additional Information:
+It is a regression in 1.2.5 (or possible 1.2.4). In 1.2.3 it worked
+perfectly fine. It also compiles fine on MS.NET 2.0
