A Bohrbug (or Bohr Bug) is an unusual software bug that repeatedly and consistently fails under specific, known conditions. For example, a bohrbug can cause a program to behave differently depending on whether it runs on a 32-bit or 64-bit system.
Because of their predictability, programmers prefer bohrbugs over other types of unpredictable and difficult-to-reproduce bugs, such as schroedinbugs.

Why is it called bohrbug?
The bohrbug was named after Neils Bohr, a famous Danish physicist who significantly contributed to the atomic theory. Essentially, the Bohr model described the atom as a small, positively charged nucleus surrounded by orbiting electrons, which orbit the nucleus in discrete energy levels. Bohr found that the number of electrons in the outer orbit determines an element’s properties.
Though it sounds simple, Bohr’s concept was instrumental in several other fields, including the liquid droplet theory (used to understand nuclear fission) and the earlier forms of quantum theory, which stated that an electron could be viewed in two ways, either as a particle or as a wave, but never both at the same time. (Although later forms of quantum theory argued the wave-particle duality that opined that an electron could be a particle, wave, both, or neither.)
The Bohr bug describes the same manifestations as an electron transitions in an atom. If an electron transitions from a higher energy field to a lower one, it collapses and emits a photon of light with a specific wavelength. Similarly, when a program attempts to access a memory location outside its scope of responsibility, it will cause the program to crash or produce unexpected results.
The bohrbug in computer programming
Bohrbugs can occur in any program, but they are more common in programs that use dynamic memory allocation. Programmers using malloc(), calloc(), and realloc() for efficient memory management are more at risk of inadvertently creating a bohrbug. If a program cannot properly manage its dynamic memory when executed, it may create a bug.
A bohrbug can cause programs to crash, data to be lost or corrupted, or dirty data to be developed. It is a security vulnerability that needs to be immediately resolved, as it can allow threat actors to execute arbitrary codes on your computer.
Borhbug vs. Heisenberg Bug
The opposite of a BohrBug is the Heisenburg bug, which, you may have guessed, is named after another physicist. Whereas a Bohrbug is predictable, a Heisenburg bug cannot be easily replicated under commonly defined conditions.
The Department of Computer Science at Rutgers University wrote an article that further differentiated Heisenbugs from Bohrbugs. Either way, because they are software bugs, they need to be detected and addressed as soon as possible.
Preventing software bugs
Unusual software bugs typically arise in the software development phase. While developing perfect software on the first try is impossible, you can take proactive strategies to reduce bugs and minimize their effects on the end-user experience.
Here are some strategies to consider to prevent software bugs:
- Prioritize code quality: Creating clean and maintainable code is essential for minimizing bugs. You can start by developing a style guide that details consistent coding standards.
- Implement code reviews: Make sure you have regular team reviews to catch potential issues before deployment.
- Utilize automated testing: Automated testing allows you to identify issues quickly.
- Maintain clear documentation: Clear documentation minimizes misunderstandings and ensures transparency across your team.
- Have regular patch management: Patch management is one of the best ways to ensure software is bug-free.
