PS - thanks for this project, much better than the original cargo asm.

index out of bounds: the len is 0 but the index is 715
I think this means it fails to find the sources. Can you run it with -vvv and see where exactly it tries to find them?

I dont understand all this output so here is a complete capture of it

At the end, just before crash it tried to read file 56, line 716
Directive(Loc(Loc { file: 56, line: 716, column: 0, extra: None }))
file 56 is defined a bit higher:
Directive(File(File { index: 56, path: FullPath("/rustc/cc66ad468955717ab92600c770da8c1601a4ff33\\library\\core\\src\\convert\\mod.rs"), md5: None }))
also printed at the beginning

This mix of forward and backward slashes looks odd :) Do you have rustc sources component installed?

This mix of forward and backward slashes looks odd :)
its pretty normal on windows nowadays. Almost everything on windows accepts / or \ as a dir delimiter. It just depends on how the path was assembled. Like this
PS C:\work\tui-textarea> ls ./asm_crash.txt
Directory: C:\work\tui-textarea
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 11/8/2023 4:38 PM 134604 asm_crash.txt
PS C:\work\tui-textarea>
see that the command used forward slash, the response has backslash
Do you have rustc sources component installed?
I dont know what that is so probably not

You install them with something like that
rustup component add rust-src

I pushed a branch called windows, can you try to install cargo-show-asm from it and run with -vvv one more time? When reading files it should print a bit more diagnostic about each file - it's actual name and how many bytes it is. You can attach the whole output or just the bit around "reading file 56".

Hmm..... I'm slowly running out of ideas :) Can you try adding your own debug printing around the file resolving place (it's in src/asm.rs, line 313 and possibly inside locate_sources method) to try to understand what's going on? I can add something to stop it from crashing, but ideally it should be able to load files if they are there...

ok, it was a different file Resolved name is "/rustc/cc66ad468955717ab92600c770da8c1601a4ff33\\library\\core\\src\\convert\\mod.rs"
somehow this file is empty, and is the only one in that directory. But now I see all files in that sparsely populated dir tree are empty.
I dont know enough about the layout of rust files or what it is you are looking for. Seems to be to do with the --rust option
from cargo-show-asm.
pacak
commented on June 2, 2024
Those files are just regular sources used to compile that specific version of the stdlib. debug info contains references to specific lines of info and cargo-show-asm decodes this info, tries to read those files, gets corresponding line and renders it when --rust option is used. So the file is there but it is empty? Not sure what's going on... Anyway, I'll try to make something that prints an error instead of panic soon-ish so you'll be able to see at least the files that are okay.

not only empty but there are like on 3 or 4 files in the entire tree of /rustc/cc...........ff33/ and they are all empty

rustup component add rust-src
Installed sources help to rust-analyzer or tools like cargo-show-asm. They don't take much space compared to a typical target folder so not much harm having it installed. Can you try installing and check if it helps?

if i remove that 0 length file all works fine, it because that locate file fn says 'if the file exists then thats the one'. I have no idea how that file got there. Maybe some other tool did something
