My favorite so far:

$ gdb -ex 'file /bin/gdb'
run
corrupted double-linked list

Thread 1 "gdb" received signal SIGABRT, Aborted.

Now,

R E A S S E M B L E

it again.

I once wrote bind_front() and move_only_function likes in C++17. This nearly drove me mad because you cannot refer to a overload set by a name.

On the otherhand, I can now decipher the template error mess that the (g++) C++ compiler spews out.

what the actual fuck. 🤮

A kernel was released that changed how the hash value got computed for casefolded filenames. (used for better windows compatibility) That kernel then went into production. This unfortunately split some file-systems that supported this into two incompatible versions, breaking the kernel rule 1.

There might now exist file-systems were created/modified with this bug present that the old/fixed kernels can’t understand.
