Subject: 29.4; JIT native compilation errors with Windows Emacs 29.4
Date: Thu, 11 Jul 2024 21:46:22 +1000

After completely removing the existing installation of Emacs and 
installing a new one from

emacs-29.4-installer.exe

there are periodic warnings that say

Warning (comp): x86_64-w64-mingw32-gcc-11.3.0: fatal error: cannot 
execute 'as': CreateProcess: No such file or directory  They 
appear to be triggered when Emacs tries to execute elisp from a 
.el with no matching .eln in the installation path (if an .eln 
*does* exist it appears to be loaded), and continue to occur 
during the Emacs session life as new bits of elisp are loaded.

Setting `native-comp-jit-compilation' to nil eliminates the warnings, which might confirm it's from the JIT process.

Do you have a libgccjit DLL on that system?

Adding Corwin, who produced the Windows installer.

Yes. As mentioned on the other thread (apologies for not knowing 
how to tie all this together) it is

c:/Program Files/Emacs/emacs-29.4/bin/libgccjit-0.dll

Thanks and regards,
