Target: Arm7V4T .NET1.1 VS2003 SP1

I am loading a 30kb XML file into a dataset:

DataSet ds = new DataSet();
ds.ReadXmlSchema(schemaReaderFile);
ds.ReadXml( readerFile);

If I run this code from the main form, then it works ok (therefore the xml
file is ok), but if I run it from the correct place, I get a
StackOverflowException.
Running it in the 4.1 emulator doesn't cause a problem, so it seems it's
specific to the target (arm7).


Any suggestions?
