Steps to reproduce Golang #31758:

# build docker image
git clone https://github.com/vitalyisaev2/pprof_cgo_issue.git
docker build -t pprof_cgo_issue

# run docker container (omit --privileged if you already have core_pattern configured)
docker run -it --name=pprof_cgo_issue --privileged pprof_cgo_issue bash

# setup core_pattern if neccessary
echo '/tmp/core.%h.%e.%t' > /proc/sys/kernel/core_pattern
ulimit -c unlimited

# launch process without profiler - works good
./pprof_cgo_issue
