Follow-up Comment #1, bug #68146 (group make):=0A=0ACorrection: my initial =
report stated that versions 4.3 and 4.4 are not=0A  affected. That was inco=
rrect =E2=80=94 I tested those versions with the system=0A  compiler (Apple=
 Clang) directly, which happens to resolve glob from=0A  libgnu.a first due=
 to link order. Sorry for the confusion.=0A=0A  The issue is not a regressi=
on between 4.4 and 4.4.1. All versions have=0A  the same fragile linking in=
 build.sh: glob() from libgnu.a is a static=0A  archive symbol, so it only =
gets pulled in if glob is still undefined at=0A  the point -lgnu is process=
ed. If any library linked before -lgnu pulls=0A  in libSystem's glob() firs=
t (e.g. additional frameworks or libraries=0A  injected by a build system's=
 C++ toolchain), the system glob wins and=0A  causes a segfault due to ABI =
mismatch.=0A=0A  The fix in the attached patch (-Wl,-force_load,libgnu.a on=
 macOS) is=0A  still correct =E2=80=94 it makes the link robust regardless =
of what other=0A  libraries are present.=0A=0A  =E2=80=94 Alexander Bayandi=
