It may be expected, but it is *not* happening. > However, I don't know why I see "??" as the function symbol in > frame 4. Why can't gdb show me the function name for that > function? Probably because there is no 'reasonable' function for gdb to print: your libstdc++ was built without debug info, and is likely partially stripped of symbols. FWIW, here is what it would have looked like if gdb were able to find proper symbol: #1 0x00b86e59 in raise () from /lib/tls/libc.so.6 #2 0x00b88882 in abort () from /lib/tls/libc.so.6 #3 0x006bd614 in __gnu_cxx::__verbose_terminate_handler () at ../../.././libstdc++-v3/libsupc++/vterminate.cc:97 #4 0x006bb005 in __cxxabiv1::__terminate () at ../../.././libstdc++-v3/libsupc++/eh_terminate.cc:43 #5 0x006bb042 in std::terminate () at ../../.././libstdc++-v3/libsupc++/eh_terminate.cc:53 #6 0x006bb17a in __cxa_throw () at ../../.././libstdc++-v3/libsupc++/eh_throw.cc:77 #7 0x080484e8 in foo () at t.cc:1 #8 0x08048509 in main () at t.cc:2 But none of this matters: everything below 'std::terminate()' is implementation detail you shouldn't care about: once 'std::terminate()' is called, you are dead.
