[SOLVED] cannot build js78 package with debug symbols

Hi
I want to report a reproducible crash of Gnome Wayland sesison and I need debug symbols for js78 package.
Building with makepkg is failing with the following error:

DEBUG: configure: error: the compiler is incompatible with the sanitization options
ERROR: old-configure failed
==> ERROR: A failure occurred in build ().
     Aborting ...

How can I solve this problem?

Re: [SOLVED] cannot build js78 package with debug symbols

Please provide the modifications you made to the PKGBUILD and the full output from makepkg.
Edit:
Did you remove -fvar-tracking-assignments from DEBUG_CFLAGS and DEBUG_CXXFLAGS as the package uses clang?

Re: [SOLVED] cannot build js78 package with debug symbols

I did not change anything in PKGBUILD. I have removed -fvar-tracking-assignments from DEBUG_CFLAGS and DEBUG_CXXFLAGS in makepkg.conf, the package was successfully built but apparently without debug symbols.
Here is the partial output of gdb after I reproduce the crash with the locally built js78 package installed:

Re: [SOLVED] cannot build js78 package with debug symbols

If you did not change anything in the PKGBUILD how did you disable stripping?

Re: [SOLVED] cannot build js78 package with debug symbols

I built a debug symbol package with 500MB of debug info which definitely gets loaded and debugs things.
