--- Comment #16 from Jack Howarth <howarth at nitro dot med.uc.edu> 2013-01-18 22:02:08 UTC --- If I compile the failing test case from comment 10 with... % g++-fsf-4.8 -static-libgcc -fgnu-tm a.C % otool -L ./a.out ./a.out: /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) the test case no longer segfaults but aborts... % ./a.out Abort Also this test case behaves the same in FSF gcc 4.6.3 and 4.7.2. The shared linkage to libstdc++ and libitm segfaults and the static linkage aborts. Note that a statically link in libgcc, libstdc++ and libitm under linux, the test case runs without error.
