Troubleshooting
Problem
Attempts to open a view of a module in IBM Rational DOORS 9.6.1.10 (or higher) gives a DXL warning which included the message "Argument 1 (32 bit int) was passed with a 64 bit value"
Symptom
The DXL interaction window contains messages such as:
-R-W- DXL: <Line:36> Argument 1 (32 bit int) was passed with a 64 bit value
-R-W- DXL: <Line:69> Argument 1 (32 bit int) was passed with a 64 bit value
Backtrace:
<Line:212>
<Line:373>
Cause
Since the Fix Pack 9.6.1.7, variables of type integer are expected to be 32-bit long (back again as it used to be in 32-bit Rational DOORS clients).
However in the particular situation described in this technote, this warning is only displayed when using Rational DOORS client 9.6.1.10 (or higher).
Diagnosing The Problem
This warning message has been introduced to warn the user when an instruction tries to set an integer variable a value greater than 32-bit. When doing so, the 4 most significant bytes are ignored as the example below demonstrates it:
int i
i = 4294967300 // 2^32 + 4
print i
In Rational DOORS client 9.6.1.10 (or higher), the output of the script above is:
-R-W- DXL: <Line:6> Assigning 64 bit value to 32 bit int

Resolving The Problem
The way to solve this problem depends on the exact cause. This technote only focuses on one possible cause: loading a view provided by IBM Rational DOORS Requirement Management Framework Add-On (RMF).
Various views provided in RMF generic model contain a layout DXL column that generates this error. For instance the view "30. Compliance Matrix" contains two such layout DXL columns: "N° §" and "satisfied by...".
The same piece of code is the cause of this warning in all the problematic layout DXL columns.
int str_end = sizeof temp
where temp is a variable of type integer.
Replacing the function sizeof by the function length solves the problem:int str_end = length temp
