Hello crvi c, could you please add an example command that you want to have completed?
And if you have changed the environment GLIBC_TUNABLES, to which value? Otherwise a gdb session driven by the two commands below could maybe point to the exact location where the overwriting takes place, if watchpoint 5 is reached, and we assume that __pthread_tunables_init is just called once... Kind regards, Bernhard cat <<EOF > /tmp/gdb-cmd.txt set width 0 set pagination off display/i \$pc set breakpoint pending on b __pthread_tunables_init run dele 1 b * (__pthread_tunables_init+30) cont dele 2 disassemble __pthread_tunables_init, __pthread_tunables_init+70 print/x \$rax print/x \$rsp + 0x8 print/x *(long*) \$2 bt b * (__pthread_tunables_init+37) cont dele 3 print/x *(long*) \$2 b * (__pthread_tunables_init+56) watch *(long*) \$2 cont info b bt full disa 4 disa 5 cont bt quit EOF gdb -q -batch -command /tmp/gdb-cmd.txt --args bash
