Not crashing on master. In fact not even hitting asserts on master.

R-Goc commented 2 hours ago

Here is a full backtrace along with failed assert, from clang 19.1.0 debug:

Assertion failed: idx < size(), file C:\Users\rysza\lib\llvm-19\llvm\include\llvm/ADT/SmallVector.h, line 305
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

Not sure why here the callstack is shorter. It looks like the assert didn't cause a trap somehow while running without lldb. The assert hit is:

   304    reference operator[](size_type idx) {
-> 305      assert(idx < size());
   306      return begin()[idx];
   307    }
