What's new in Klocwork 2019.3
Here are the highlights for Klocwork 2019.3. If you're upgrading, also see the Limitations for items that affect how you use Klocwork.
New C/C++ checkers
- The CWARN.DTOR.VOIDPTR checker detects and reports instances of the C++ operator delete used with an operand that has the type 'pointer to void'. Calling delete with an operand of this type will bypass the underlying object destructor call, and can result in memory and resource leaks.
- The UNUSED.FUNC.STL_EMPTY checker detects and reports instances of calls to the empty() method of standard C++ container classes, in cases when the value returned from the call is ignored. This checker helps programmers catch instances where they've accidentally called the empty() method instead of the clear() method, which can result in serious and hard-to-find algorithmic bugs.
MISRA C 2012 new rules
Our enhanced coverage for MISRA C 2012 now includes checkers to support Rules 5.8 and 5.9.
Improvements to supported compilers
We've improved support for the following compilers:
- Clang
- GNU
For the full list of supported C/C++ compilers, see C/C++ compilers supported for build integration.
Analysis engine enhancement
Building on our history of continually improving our analysis engine, we've enhanced our implementation 64-bit architecture on Linux, allowing Klocwork to more effectively analyze very large and complex code bases and projects.
Licensing
2018 licenses are not compatible with Klocwork 2019.3. You need a new license to use the latest version of the product. Contact license@roguewave.com to obtain a new license.
Checker improvements
From release to release, we improve issue detection to bring state-of-the-art capabilities to our customers. As a result, expect your analysis results to change as accuracy and coverage improve.

|---|---|
| CWARN.DTOR.VOIDPTR | Delete expression with an object of type pointer to void |
| MISRA.IDENT.NONUNIQUE.EXTERNAL.2012 | Implements MISRA C 2012 Rule 5.8: Identifiers that define objects or functions with external linkage should be unique. |
| MISRA.IDENT.NONUNIQUE.INTERNAL.2012 | Implements MISRA C 2012 Rule 5.9: Identifiers that define objects or functions with internal linkage should be unique. |
| UNUSED.FUNC.STL_EMPTY | Ignored return value of an STL object empty() method |
Enabled or disabled checkers

- UNUSED.FUNC.STL_EMPTY
Taxonomy improvements
As part of our installation, we offer several custom taxonomy files that map our checkers to standards such as MISRA, CWE, OWASP and DISA STIG.
| Taxonomy | Updates |
|---|---|

misra_c_2012_c90.tconf and misra_c_2012_c90_ja.tconf misra_c_2012_with_amd1_c90.tconf and misra_c_2012_with_amd1_c90_ja.tconf |
We added references to the following checkers: MISRA C 2012 Rule 5.8: Identifiers that define objects or functions with external linkage should be unique.
MISRA C 2012 Rule 5.9: Identifiers that define objects or functions with internal linkage should be unique.

Developer Network
In October, 2018, the Rogue Wave Support Center at https://techsupport.roguewave.com/ was upgraded to include Klocwork. As part of that transition, Developer Network will no longer be available after November 30, 2019.
End of support announcements
Klocwork 2019.3 is the last supported release of the Vim plug-in.
Klocwork 2018.3 was the last supported release of the Klocwork Portal and License Server on the following platforms: AIX, Mac, and Solaris. Rogue Wave is also here to help! If you need help moving your Klocwork Portal or License Server to Linux or Windows, you can contact Rogue Wave Professional Services to discuss assistance via a services engagement.
Portal licensing changes in Klocwork 2020
As of 2020, Klocwork will implement additional licensing checks related to the Portal. We recommend you validate your Portal licensing needs now to ensure you have a sufficient number going into the next release.
