Dunno how to reduce or bisect that:

g++ pr107519.ii -c -Ofast -std=c++23 -s -flto -march=native -fmodules-ts -c
In module imported at iobuf_file.cc:1:1:
./../../../include/fast_io.h: error: failed to read compiled module: No such
file or directory
./../../../include/fast_io.h: note: compiled module file is

./../../../include/fast_io.h: note: imports must be built before being imported
./../../../include/fast_io.h: fatal error: returning to the gate for a
mechanical issue
compilation terminated.

Does it reproduce w/o -fmodules-ts ?
