Some (mostly generated) files from https://github.com/mamedev/mame take several minutes to compile with `-fsanitize=undefined` - e.g. `src/devices/cpu/m68000/m68000-sdf.cpp`.
They also consume a lot of memory during compilation:
```
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
3190941 user 20 0 2333788 2,1g 151380 R 100,0 14,1 1:00.92 clang++
```
I do not now what information to provide for this to proceed so I am waiting for feedback.
IIRC this also applies to `-fsanitize=address`.
