Description
We can see from the screenshot that the analysis creates a function at 0x40100b, but it is really just part of the main function:
This breaks the decompilation because the stack resolution is not working properly after that
binary: blue wizard writes eagerly

Research direction
Reproduce the issue with the “blue wizard writes eagerly” binary and inspect the analysis around 0x40100b, where a function is incorrectly identified inside the main function. Done means the spurious function is no longer created and decompilation retains correct stack resolution afterward.
