Hi Mathieu,

That works for me (i.e., =E2=80=98gcc=E2=80=99 runs to completion just fine=
.)

But I suppose this depends on what=E2=80=99s in ~/.guix-profile/lib.  If you
have a conflicting GCC version there (which is not the case for me), it
could break.

Could you run the snippet you provided above with =E2=80=98--verbose=E2=80=
=99 passed to
=E2=80=98gcc=E2=80=99?  That will allow us to see what libraries and tools =
it picks up.

What makes you think =E2=80=98ld-wrapper=E2=80=99 is involved?

Anyway, the =E2=80=98--verbose=E2=80=99 output should give us more insight.

Thanks,
Ludo=E2=80=99.
