Possible disadvantages of OllyDbg

• Windows Only
  OllyDbg is designed exclusively for the Windows operating system, limiting its use across different platforms.
• No 64-bit Support
  The debugger primarily focuses on 32-bit applications and offers limited support for 64-bit applications, which can be a significant limitation for modern software analysis.
• Limited Scripting
  While OllyDbg supports scripting to some extent, it is not as advanced as some other debuggers that offer more robust automation capabilities.
• Steeper Learning Curve for Advanced Features
  Although it has a user-friendly interface, mastering OllyDbg's more advanced features can be challenging for newcomers.
• Inconsistent Updates
  The development and updates for OllyDbg have been sporadic, leading to concerns about long-term support and missing out on modern features.

Possible disadvantages of GNU Project Debugger

• Steep learning curve
  New users may find GDB's command-line interface challenging to use due to its complexity and large set of commands, which requires time and effort to learn efficiently.
• Limited GUI support
  While GDB primarily operates via a command-line interface, there are limited GUI front-ends, which might not provide the same level of user-friendliness as modern IDEs for some users.
• Performance overhead
  Debugging with GDB can introduce performance overhead, especially in large applications, potentially resulting in slower execution speeds during the debugging session.
• Complex setup for remote debugging
  Setting up GDB for remote debugging can be complex and requires additional configuration, which might be cumbersome for users unfamiliar with network programming.
• Sparse error messages
  Error messages provided by GDB can sometimes be terse or cryptic, making it difficult for users to quickly understand the issues without further investigation.
