rustix error when building helix #938
Description
When trying to build helix from source as an experiment, I encountered this error:
libgccjit.so: error: : gcc_jit_block_add_assignment: mismatching types: assignment to input_register (type: __int8_t *) from (void *)loadedValue2 (type: void *)
error: failed to build archive at `helix/target/debug/deps/librustix-f2aafd20cac1c040.rlib`: failed to open object file: No such file or directory (os error 2)
This seems to be similar to #792 which was closed by #874.

Looks like #874 should indeed fix this issue but it only was available in a single toolchain (nightly-2026-08-04) and every subsequent toolchain don't include the fix.
Once rust-lang/rust#162499 is merged and released in a toolchain then it should work.

This seems to be fixed, so closing.
Feel free to reopen if you still have this issue.
(But there seems to be a later error that prevents building helix.)
