Crash Report - Arch Linux

[ancientjpeg]

Reporting a crash I've encountered in LLDB. Seems to only occur when I exit LLDB. I'm running LLDB using lldb-dap through neovim on Arch Linux. Here's the stack trace:

free(): invalid pointer
PLEASE submit a bug report to  and include the crash backtrace.

[EugeneZelenko]

Could you please try 19 or main branch?

[ancientjpeg]

Thanks for your reply Eugene. At the moment I’m using the LLVM distributed through the AUR, which does not yet have a version for clangd-19 available. If I get the time I’ll attempt to build from source and report back.

[foonathan]

I have a minimal reproducer for this, also clang 18.

Source file:

int main() {
    auto ptr = new int[10];
    ptr[11] = 11;
}

Commandline:

$ clang -fsanitize=address test.cpp
$ lldb ./a.out
