ISIM crashes when the assert command and the 'delayed attribute are used inside the same process.
This error is received in the testbench.:
Removing the line with the 'delayed attribute from the above code will not result in any errors.
The code will also work if the line containing the assert command is commented out.
This can be used as a workaround but it always prints the sentence.
This seems to be a compilation error from the VhdlExpr.cpp library.
