It might be the sign of some compiler-dependent logic/code. We don't catch it with MSVC because those tests run only on Linux, and both GCC and Clang often replicate each other's behavior. cc @yossizap

Updated the issue, now only 3 debug tests are broken with TinyCC.

[XVilka]

It was fixed in the latest dev: https://github.com/rizinorg/rizin/runs/3287509910#step:12:749

In the #1414 I will enable TinyCC tests to be checked again.
