On arch, have to hit ^C 4 times or the GUI never opens

Environment

So 22. června 2024, 12:39:30 CEST
radare2 5.9.2 0 @ linux-x86-64

iaito is installed from arch repos

Description

When I open an elf, it stays stuck with no CPU activity or output, no windows open, seemingly forever (I lost patience, maybe it proceeds after some minutes).

It is 100% replicable for me.

Test

sample file I tried to open, zipped because github hates elf

sample.elf.zip

You can lower the analysis depth level.

thanks for sharing the binary ive never find a sample that shows this error before and i will fix it properly

[MightyPork]

Yes with aa it opens instantly, I didn't think it'd be useful to lower it, I remember using aaaa before and it worked fine.

The binary is a firmware for a stm32 microcontroller

[trufae]

its once again the same dbginfo bottleneck passing this flag -e bin.dbginfo=false makes the analysis finish quickly.

[trufae]

i dont get the 'Execution stopped on unaligned instruction' in r2 from git :?

[trufae]

nvm i can repro. the dbginfo bug was macos-only, on linux i get the error message

[trufae]

There are several issues some of them fixed:

• the console redirector seems to hang on qt6 ( can u try running with qt5)
• The message is printed so many times and this warning exposes a bug that is now fixed in r2

Need to investigate in the qt bug but thats outside my scope rn

[trufae]

i think the qt6 bug should be workarounded with the latest changes in r2 and iaito, can you give it a try? i don't have plans to make a release on both tools yet. but if its a blocker i can tag 5.9.4

[MightyPork]

I built iaito from git now and the sample file opens just fine almost immediately, even with aaaa :+1:

[trufae]

Cool thanks for testing!
