Compiler bug in current jenkins' ARM compiler
Our current version of ARM compiler running on jenkins is having the following gcc issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119
As we are in the process of enabling -Wall -Werror, this warning generated due to the bug gets converted into an error and the build fails.
A patch was provided for libosmocore code to fix compilation in case the bug is triggered, see https://gerrit.osmocom.org/#/c/2955
Best option would be to either patch&rebuild the gcc-arm used on jenkins or update it to a newer version, as we may hit this issue later with other osmocom projects and more patches will need to be provided.
