Every call of a function in an inferior process fails. Just before
printing `program no longer exists' the state of gdb looks like this.
ecs->ws = {kind = TARGET_WAITKIND_SIGNALLED, value = {integer = 11,
sig = TARGET_SIGNAL_SEGV, related_pid = 11,
execd_pathname = 0xb <Address 0xb out of bounds>, syscall_id = 11}}

Constructing function calls manually (using `set va', 'j', and `b
<where function should return>') works.
Since many other features of gdb work normally, I am able to retrieve
further information about gdb state while trying to call function in
an inferior process. Will do so on request.
