TypeMock + dotCover 2.2 results in BadImageFormatException

Hi we are considering replacing ncover with jetbrains dotCover 2.2
Running TypeMock 7.2.5.0

But we are getting some consistent exceptions when reaching a special class when typemock + dotcover is enabled

System.BadImageFormatException : Bad method token.
   at FancyNamespace.UnitConvert.Convert(T inputValue, Unit fromUnit, Unit toUnit)
   at FancyNamespace.UnitConvert.Convert(ValueUnit inputValue, Unit toUnit) in UnitConvert.cs: line 171
   at FancyNamespace.Tests.UnitConvertTest.Assert(Decimal expected, Decimal originalValue, Unit fromValue, Unit toValue) in UnitConvertTest.cs: line 93

public static class UnitConvert
{
      public static ValueUnit Convert(ValueUnit inputValue, Unit toUnit)
      {
         return new ValueUnit(Convert(inputValue.Value, inputValue.Unit, toUnit), toUnit);
      }

      public static decimal Convert<T>(T inputValue, TUnit fromUnit, TUnit toUnit) where T : IConvertible
      {
             // Snip
      }

If we rename one of the Convert methods, tests start to work again.
If we disable TypeMock then the tests work again.
If we disable dotCover then the tests work again.
