[srslte-users] srsENB crashes with phone, not with srsUE

[Ayman Maghrabi]

Thank you Andre for the help. I've been wanting to use gdb with srsLTE but
didn't really know how to do that. I was able yo follow your instructions
and it appears that my code is causing an issue with one of the existing
vectors:

Thread 32 "STACK" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffa31af700 (LWP 29104)]
0x00005555556ba540 in std::vector<srsenb::sched_cell_params_t,
std::allocator<srsenb::sched_cell_params_t> >::operator[] (this=0x0, __n=0)
    at /usr/include/c++/7/bits/stl_vector.h:816
816 return *(this->_M_impl._M_start + __n);

At least I know what to look for. Thanks again.

Regards,
Ayman
