Comment 5 for bug 1971114

Hi all,

i also ran into this bug and have solved the issue according: https://bugzilla.redhat.com/show_bug.cgi?id=1893533#c2

Debian LTO page: https://wiki.debian.org/ToolChain/LTO, mentions that you can simply disable LTO using:

export DEB_BUILD_MAINT_OPTIONS=optimize=-lto

in the debian/rules file.
So i downloaded the source package and added the flag and rebuilded the package which solves the problem for me.

Simple test case to reproduce:

apt install python3-grpcio
GRPC_VERBOSITY=debug python3
Python 3.10.6 (main, May 29 2023, 11:10:38) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import grpc
>>> channel = grpc.insecure_channel('127.0.0.1:1234')
^Z
[2]+ Stopped GRPC_VERBOSITY=debug python3

if you hit enter nothing appears on screen and you cannot exit the process using ctrl+c

after the rebuild of the package i get:

GRPC_VERBOSITY=debug python3
Python 3.10.6 (main, May 29 2023, 11:10:38) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import grpc
>>> channel = grpc.insecure_channel('127.0.0.1:1234')

So can the option 'export DEB_BUILD_MAINT_OPTIONS=optimize=-lto' be added to the rules file?
Otherwise this package is not working at all.
