[Mono-dev] gmcs crashing

[Arno Rehn]

Hi,

when I try to compile the KDE-Mono bindings, gmcs crashes with the following:

$ /opt/mono-1.9/bin/mono --debug /opt/mono-1.9/lib/mono/2.0/gmcs.exe -r:/usr/lib/mono/2.0/qt-dotnet.dll 
*.cs -warn:0

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

  at Mono.CSharp.Driver.Main (System.String[] args) [0x0001f] 
in /data1/src/mono/mcs/mcs/driver.cs:295

I'm sorry but I can't provide more information or an actual test case at the 
moment, since the KDE classes are quite large and numerous and tracking it 
down would take much too long.
The patch attached fixes this bug, though I don't know if it's only the 
symptoms being fixed.
Is there any way to get more debug output from gmcs, i.e. which class it's 
currently processing?
