Injector overflowed sigaltstack

Any time I run ./sifter.py --unk --dis --len --sync --tick -- -P1 -t it crashes, normally with no output. Changing to random mode significantly increases the speed that it crashes at, but it still does in tunneling mode (I have not tested bruteforce). The only error messages I get are from dmesg and are as follows

[ 3154.421293] signal: injector[11197] overflowed sigaltstack
[ 3154.421298] signal: injector[11197] overflowed sigaltstack

What else can I do to debug?

My system is setup like so:
uname -srmo: Linux 5.13.8_1 x86_64 GNU/Linux
lscpu: here
