Error: data file contains a repeated location (1)

[hacknus]

When running dhat 0.3.2 with rustc 1.68.0 (2c8cc3432 2023-03-06) on my MacBook Pro with apple silicon and the following configuration:

#[cfg(feature = "dhat-heap")]
#[global_allocator]
static ALLOC: dhat::Alloc = dhat::Alloc;

fn main() {

    #[cfg(feature = "dhat-heap")]
        let _profiler = dhat::Profiler::new_heap();
    #[cfg(feature = "dhat-heap")]
        println!("lets profile!");
    ...
}

I get the following output:

dhat: Total:     2,197,613,072 bytes in 140,839 blocks
dhat: At t-gmax: 84,232,363 bytes in 22,743 blocks
dhat: At t-end:  4,467,522 bytes in 256 blocks
dhat: The data has been saved to dhat-heap.json, and is viewable with dhat/dh_view.html

but when trying to open the json file either in the web viewer or with with the html from the cloned repo, I get the following error:
Error: data file contains a repeated location (1)

The json itself is attached.
dhat-heap.json.zip

Another file with this issue:
dhat-heap 4.zip

Code: https://github.com/LemmyNet/lemmy/tree/08e835d487b983c44ce2570d8c396d570d426916

I used cargo run with debug profile

Hello, I am getting the same error. I was able to bypass it by editing the dh_viewer javascript code to suppress the exception but instead I get a different error:

It appears dhat-rs may be outputting bad json under certain circumstances but the issue is not obvious to me due to my lack of knowledge with dhat. More specifically with with pp frame data

Same error here on Linux x86_64
