SIGSEV error during parsing html

[ReyPJ]

So I was using nvim without problems but when I opened a HTML file neovim crash, I ran a coredumpctl, and the backtrace indicates that the error occurred during a memory free operation, related to the external scanner of Tree-sitter for HTML, I already try to uninstall and reinstall the parser and in :checkhealt nvim-treesitter the HTML parser is OK

checkheatl outpo:

`nvim-treesitter: require("nvim-treesitter.health").check()

I already uninstall de parser and installed it again

guaranteed you're using an older parser version, ensure you're using it built from the latest version

Hey, I have also encountered this error, but when I do :TSUpdate it shows All parsers are up-to-date! I have a video of it happening here https://github.com/nvim-treesitter/nvim-treesitter/issues/6730

@amaanq, I'm running into the same issue.

:TSUpdate html shows that Parsers are up-to-date!

When it crashes, it prints on the screen:

nvim(77752,0x119e07600) malloc: *** error for object 0x6d69766f656e2f72: pointer being freed was not allocated nvim(77752,0x119e07600) malloc: *** set a breakpoint in malloc_error_break to debug

It only happens with the HTML parser installed.

When the parser is uninstalled, nvim no longer crashes on HTML files.

I solved this by building the HTML parser from source

@TarunDaCoder, I caught that from your open issue #6730 on nvim-treesitter.

I think a better solution would be to delete the entire nvim cache directory, as this issue could have been caused by corrupted nvim cache files. Then reinstall all plugins, and allow nvim to recreate any necessary cache files when it runs.
