           Summary: Cannot compile Berkeley DB for .NET
           Product: Mono: Compilers
           Version: 1.2.6
          Platform: x86
        OS/Version: Ubuntu
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at ximian.com
        ReportedBy: karl at waclawek.net

This was seen on Ubuntu 7.10 with Mono 1.2.6 preview 3.

Depending on the order of the source files passed to gmcs, the compiler crashes
with different kinds of exceptions. To reproduce:

1) Get source code from CVS: 
   cvs
-d:pserver:anonymous at libdb-dotnet.cvs.sourceforge.net:/cvsroot/libdb-dotnet
login

  hit Enter (empty password).

  cvs -z3
-d:pserver:anonymous at libdb-dotnet.cvs.sourceforge.net:/cvsroot/libdb-dotnet co
-P libdb-dotnet

2) cd to src directory

3) open a terminal and run xbuild libdb_dotNET45.csproj
This will report success, but there is no assembly generated (bug in xbuild, I
guess). Then copy the gmcs commandline generated by xbuild (and written to the
console) back into the terminal and apply the fix for xbuild bug #347187
(define symbols), the command line should look like this (quotes around the
defines symbols):

gmcs /noconfig /debug:full /debug+ /optimize- /out:bin/Debug/libdb_dotNET45.dll
Properties/AssemblyInfo45.cs DB_LOCK.cs DB_LOCK_WRAP.cs DB_LOG.cs
DB_LOG_WRAP.cs DB_MPOOL.cs DB.cs DB_ENV.cs DB_ENV_Wrap.cs DB_MPOOL_WRAP.cs
DB_SEQUENCE.cs DB_SEQUENCE_Wrap.cs DB_TXN.cs DB_TXN_Wrap.cs DB_Wrap.cs DBC.cs
DBC_Wrap.cs Common.cs DBT.cs LibDb.cs Util.cs XA.cs /target:library /unsafe+
/define:"TRACE;DEBUG;BDB_PACK8;BDB_4_5_20;_USE_32BIT_TIME_T"
/reference:/opt/mono-1.2.6/lib/mono/gac/System/2.1.0.0__b77a5c561934e089/System.dll
/warn:4

Running this will result in gmcs crashing with an unhandled exception:

Unhandled Exception: Mono.CSharp.InternalErrorException: DB_MPOOL.cs(111,16):

Now, move the file Common.cs to another (earlier) position in the command line,
like this:

gmcs /noconfig /debug:full /debug+ /optimize- /out:bin/Debug/libdb_dotNET45.dll
Properties/AssemblyInfo45.cs Common.cs DB_LOCK.cs DB_LOCK_WRAP.cs DB_LOG.cs
DB_LOG_WRAP.cs DB_MPOOL.cs DB.cs DB_ENV.cs DB_ENV_Wrap.cs DB_MPOOL_WRAP.cs
DB_SEQUENCE.cs DB_SEQUENCE_Wrap.cs DB_TXN.cs DB_TXN_Wrap.cs DB_Wrap.cs DBC.cs
DBC_Wrap.cs DBT.cs LibDb.cs Util.cs XA.cs /target:library /unsafe+
/define:"TRACE;DEBUG;BDB_PACK8;BDB_4_5_20;_USE_32BIT_TIME_T"
/reference:/opt/mono-1.2.6/lib/mono/gac/System/2.1.0.0__b77a5c561934e089/System.dll
/warn:4

Recompile, gmcs crashes with another unhandled exception:
