While trying to walk through the unwinder under darwin9 in current gcc trunk, I
discovered that we are now linking against multiple libgcc in all of the shared
libraries...
otool -L libffi.4.dylib
libffi.4.dylib:
/sw/lib/gcc4.5/lib/libffi.4.dylib (compatibility version 5.0.0, current
version 5.1.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version
1.0.0)
/sw/lib/gcc4.5/lib/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.4)
except for /usr/lib/libgcc_s.1.dylib itself. This is very bad and breaks the
ability to
walk through the unwinder in darwin9 (which works in gcc 4.4.2 that doesn't
show
this problem).
