Solve the Error “corrupted size vs. prev_size” glibc

C++ is a general-purpose powerful programming language, which is popular to develop games, browsers, operating systems, web applications, and other web programs. The compiler of C++ is user-friendly, and programmers easily compile the codes. When you are working with the language to design a project for the website, you can encounter errors as well. Errors are common no matter what language you use for programming, the same goes for c++. You may get the error warning “corrupted size vs. prev_size” glibc.

Here, in this article, we will guide you on how to solve the error and what measures you need to follow to fix it. But, before that, we will discuss how the error occurs.

How the error pops up

The cause of the error warning is implementing a JNA bridge to FDK-ACC. When you do that, the error shows. Check out the code

How to fix “corrupted size vs. prev_size” glibc

To overcome the error warning, you need to understand the cause.  It happens when structured fields controlled by the memory chunk in the adjacent following chunk are overwritten because of the out-of-bounds access by the code. This is the reason you get the error warning when compiling the code. The different chunk size from the next chunk control structure needs to be checked when you encounter the error.

Quick Solution

The error can be solved by simply disabling the alignment. The Java/JNA layer has been through the structural mapping that advised different #pragma related to alignment/padding from where it used the dll/so to compile. Here, you get the data that caused the error, which is written beyond the structure boundary allocated.

This is the best solution you can do to get the error fixes. You just need to disable the alignment.

Conclusion

We shed light on the solution to fix the “corrupted size vs. prev_size” glibc. The solution is powerful enough to help you remove the error.

I wish you happy coding with no errors!
