-------------------------+-------------------------
 Reporter:  Chris Johns  |      Owner:  Chris Johns
     Type:  defect       |     Status:  assigned
 Priority:  normal       |  Milestone:  4.11.2
Component:  RSB          |    Version:  4.11
 Severity:  major        |   Keywords:  RSB
-------------------------+-------------------------
 Building LM32 on Windows crashes the RSB with a long path. The
 `os.listdir` call in Python on Windows is limited to 254 characters even
 if the path is Uncode.
