'use of undefined value' with JIT

[november-kilo]

I see an error message in the DGD console using latest from dgd and lpc-ext repositories (only JIT extension is used) and my cloud-server fork (also occurs in base cloud-server repository with the same changes) using my mac. The message appears only once with a new cache.

I'm unable to try on another computer for a while.

Procedure:

• create cache/ in jit extension
• boot mud
• log in as admin, grant a user access
• log in as that user
• type foo
• message in DGD console

  cache/ca/ca5af742ad29b8c4074b06877db045b8.ll:157:41: error: use of undefined value '%t10'

Haven't been able to reproduce it exactly yet, but another error popped up that could be caused by a JIT compiler problem.

It seems like you are using macOS 10.14 but with older Xcode?

[dworkin]

Reproduced on 10.13 with Xcode 10.1.

I'm using macOS version 10.14.6

I use the Xcode standalone command line developer tools. I removed them and installed with xcode-select --install. I get xcode-select version 2354, which is the same as before, and the same results after recompiling DGD and LPC-ext. Perhaps it doesn't install the correct command line tools for this mac.

I just now installed Xcode 11.3.1 but haven't figured out how to use it yet.

[dworkin]

I can reproduce it with Xcode 11.3.1 now.

This is actually a DGD issue.
