I managed to compile the gdb debugger for the target architecture and run under gdb That's what he gave me : This GDB was configured as "mips-unknown-linux-gnu". For bug reporting instructions, please see: <http://www.gnu.org/software/gdb/bugs/> ... Reading symbols from / bin / ssh...done. (gdb) run Starting program: / bin / ssh Program received signal SIGSEGV, Segmentation fault. 0x555887e0 in?? () I also tried to run ssh with -vvv. With the same result. I also did an experiment . Replaced the source code to the stub ssh.c "hellow world", the program also issued a segmentation fault. I'm not sure but it may be a bug associated with the correct configuration at compile time. I tried to configure with default settings , but there were errors . I had to add two flag -fPIC-shared. Finally make looks like: make LDFLAGS = "-shared-L.-Lopenbsd-compat /-fstack-protector-all" CFLAGS = "-fPIC-g-O2-Wall-Wpointer-arith-Wuninitialized-Wsign-compare-Wformat-security-Wno-pointer -sign-Wno-unused-result-fno-strict-aliasing-D_FORTIFY_SOURCE = 2 -fno-builtin-memset-fstack-protector-all On 05 ???. 2014 ?., at 14:19, Darren Tucker <dtucker at zip.com.au> wrote: > On Sun, Jan 5, 2014 at 8:10 PM, ANDREY ROZE <roseandrew at me.com> wrote: >> I unfortunately I am unable to run under gdb debugger as it must also be compiled.
