Closed

Description

@radare

Ghidra and IDA fails in this simple hello world. r2 is not failing because is not really trying to find the size of the variable. here's the bin and some random screenshots.

    @trufae What is this issue really about?
    Is it a bug in r2? Is it a feature request?

    To me this seems about the decompiler, but r2 is not really a decompiler so this doesn't seem relevant.

    It’s about variable access analysis. This info is used by the decompilers indeed. But the analysis is done in r2
