I completed testing of various options around the segmentation issue with gnat. Below, gcc uses 2 shared objects while gnat uses 4.
$ otool -L gcc
gcc:
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)
$ otool -L gnat
gnat:
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
/opt/gcc-4.9.x/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.20.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1197.1.1)
/opt/gcc-4.9.x/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
This requires make bootstrap. The --disable-bootstrap option means that gcc will look like gnat above.
Yet, an other solution, change ...
--with-host-libstdcxx="-lstdc++"
To ...
--with-stage1-ldflags="-lstdc++"
Here, an extract of the relevant section from the 'Makefile' after running configure.
# Linker flags to use on the host, for stage1 or when not
# bootstrapping.
STAGE1_LDFLAGS = -lstdc++
# Libraries to use on the host, for stage1 or when not bootstrapping.
STAGE1_LIBS =
# Linker flags to use for stage2 and later.
POSTSTAGE1_LDFLAGS = -static-libstdc++ -static-libgcc
# Libraries to use for stage2 and later.
POSTSTAGE1_LIBS =
I am not sure why one has to specify --with-host-libstdcxx="-lstdc++" or --with-stage1-ldflags="-lstdc++" for gnat and friends to not segfault. Please consider this as a work-around. It has taken me 2 weeks to reach this point (mainly from running 2 cores).
Notice how gnat and friends are still linked to libstdc++ and libgcc_s.1 after running make bootstrap-lean.

My testing (towards the end) has been against a snapshot from the 4.9 branch.
