Since it seems a pipe problem i've tried to force cscc to not spawn plugin with 
pipe in line 1291 of cscc.c :

1289   -      DumpCmdLine(cmdline);
1290   -      status = ILSpawnProcessWithPipe(cmdline, ...);

became:

1290   -      status = 0;

so that cscc think the platform can't use pipes and run plugin not using them.
Rebuilding cscc that way the segfault goes away and cscc correctly handle the 
multiple definition error. So the problem is the way the pipes are used.

Summary:  Segmentation fault on duplicated definition for overriden methods

Original Submission:  I've refined the circumstances in which the bug is 
observable.
Cscc segfaults when a subclass does 2 definition for an overriden method. 
Attached is a dummy.cs file modified. Put it in pnetlib/samples instead of the 
old dummy.cs and run make.
If you try to compile only dummy.cs it will complain about duplicate definition 
in wrong way ( stdin:<wrong line number>: instead of dummy.cs:<correct line 
number>: ) but it will *not*  give segmentation fault.

This dummy.cs file has to be substituted to the one in pnetlib/samples. After 
the substitution run make and you'ìll reproduce the segmentation fault.
