Description of Problem:
gmcs crashes when a few of the source files given on the command line aren't in
a specific order

Steps to reproduce the problem:
I couldn't track the problem down to create real test cases. Sorry.

Actual Results:
pumphaus ~/dev/KDE/kio $ /usr/bin/mono --debug /usr/lib/mono/2.0/gmcs.exe
-out:kio.dll -r:qt-dotnet,../csnew/kde-dotnet.dll -target:library -warn:0
KIO_Job.cs KIO_SimpleJob.cs KIO_TransferJob.cs *.cs

Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object

If a specify an additional source file, it works fine.
pumphaus ~/dev/KDE/kio $ /usr/bin/mono /usr/lib/mono/2.0/gmcs.exe -out:kio.dll
-r:qt-dotnet,../csnew/kde-dotnet.dll -target:library -warn:0 KIO_Job.cs
KIO_SimpleJob.cs KIO_TransferJob.cs KIO_SlaveInterface.cs *.cs
pumphaus ~/dev/KDE/kio $

It shouldn't be necessary at all to put any sources at the beginning - the file
list created by bash is supposed to work fine as well.

Expected Results:
No crash, a simple compilation without any output.

How often does this happen? 
Every time I don't put one of those source files at the beginning of the file
list.

Additional Information:
I also saw this behaviour in mono 1.9 from branches/mono-1-9 (rev 95040).
