Introspector build fails for glib-based projects

[jluebbe]

The introspector build for glib itself fails with:

Step #6 - "compile-libfuzzer-introspector-x86_64": Checking if "GCC size_t typedef is long" compiles: NO
Step #6 - "compile-libfuzzer-introspector-x86_64": 
Step #6 - "compile-libfuzzer-introspector-x86_64": meson.build:1692:2: ERROR: Problem encountered: Could not determine size of size_t.
Step #6 - "compile-libfuzzer-introspector-x86_64": 
Step #6 - "compile-libfuzzer-introspector-x86_64": A full log can be found at /work/meson/meson-logs/meson-log.txt

Some other projects building glib as a meson subproject fail with the same issue:

• cario
• fwupd
• ostree
• rauc

Fuzz and coverage builds work fine, though.

For bluez, glib is built during the container creation instead of via build.sh, which avoids this issue.

The docs recommend static linking, but I'm not sure if there are benefits to compiling the subprojects with the sanitizer options.

How/where should this be fixed?

I suspect this is related to meson which have also been discussed in #7540 (comment) -- I need more looking into this though.
