Crash when compiling from a Zed task while saving

I was doing a compilation using a keyboard shortcut I had configured as follows in Zed:
``` "action::Sequence", ["workspace::SaveAll", "workspace::Save", "debugger::Rerun"],```
Effectively, save everything then run the debugger. The debugger run has an initial stage that will run the compilation which is how clang got invoked.
I was messing around with trying to get it to save things before running the builds and it wasn't working right for me. I suspect the sequence actions used within Zed involve some degree of asynchronicity. With only the `workspace::SaveAll` part (meaning without the `workspace::Save` part), the build would start before the file write had happened and not rebuild.
Since I think this is unrelated to the code being compiled I haven't included the requested source and build script. I made sure it didn't repro running the script and I've kept it. I'm willing to share privately with a compiler dev but not more publicly.
