- The CI machine doesn't have llvm-symbolizer available in PATH, so addr2line
is used instead, but the Ubuntu 22.04 version doesn't support the DWARF used in
the test program:
- `addr2line: DWARF error: invalid or unhandled FORM value: 0x23`
- Possible fixes:
- Make llvm-symbolizer available in PATH
- Upgrade to Ubuntu 24.04
- Modify the tests to use DWARF 3 instead of 4
The macOS builder fails to build the sanitizer tests:
```
ld: warning: ignoring duplicate libraries: '-lc++'
Undefined symbols for architecture arm64:
"std::__1::__hash_memory(void const*, unsigned long)", referenced from:
...
```
It seems some object files were compiled for LLVM 22 (git) but when linking the
system libc++ is used, which doesn't have `std::__hash_memory`, introduced in
LLVM 21 IIRC.
This failure doesn't appear to be related to this PR.
