+Bug#: 58560
+Product: Mono: Runtime
+Version: unspecified
+OS Details: Fedora Core 1 with all current updates
+Status: NEW   
+Priority: Major
+Component: misc
+AssignedTo: mono-bugs@ximian.com                            
+ReportedBy: 1@234.cx

+TargetMilestone: ---
+Summary: Poor interaction between Mono and NPTL.
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+When using Mono on an NPTL-enabled system, various problems occur which
+seem to be indicative of race conditions.  For example, sometimes programs
+segfault, other times unexpected exception messages appear.
+Steps to reproduce the problem:
+1. Go to a machine with NPTL enabled such as Fedora 1.
+2. Run XSP, for example "mono /usr/bin/xsp.exe"
+3. Download a page so that the page compiler will be executed.
+4. Press return to stop the server.
+Actual Results:
+Exception messages appear and the server often locks up.
+Expected Results:
+The server should simply exit when return is pressed, without exceptions
+being thrown.
+How often does this happen? 
+As far as I can tell, always, but the exact exceptions are often different.
+ This is what leads me to think that there is a race condition.  I also had
+a problem where Mono applications simply segfaulted as soon as I tried to
+start them.
+Additional Information:
+I think this is connected with NPTL because everything works properly when
+I set LD_ASSUME_KERNEL=2.4.1.
