Description

Wails application crashes when executing a gRPC request.
The problem seems to happen only on Linux, on macOS the requests are executed well.
Also plain non-gRPC HTTP requests are executed well on any kind of a system.

signal 11 received but handler not on signal stack
fatal error: non-Go code set up signal handler without SA_ONSTACK flag

runtime stack:
