libosmocore does not build in Ubuntu

Hi, Can someone here help me debug the failing build of libosmocore in Ubuntu? See: https://launchpadlibrarian.net/235791225/buildlog_ubuntu-xenial-amd64.libos… The test case "gprs-bssgp" fails with following output: stderr: MESSAGE to 0x7f0000ff, msg length 12 02 00 81 01 01 82 0b 56 04 82 0b 55 All NS-VCs for NSEI 2901 are either dead or blocked! All NS-VCs for NSEI 2901 are either dead or blocked! BSSGP BVCI=0 Rx BVC STATUS, cause=Protocol error - unspecified BSSGP BVCI=1234 Rx BVC STATUS, cause=Unknown BVCI NSEI=2901/BVCI=2989 Cannot handle PDU type 34 for unknown BVCI, NS BVCI 2989 Unable to resolve NSEI 4660 to NS-VC! Assert failed rc >= 0 gb/gprs_bssgp_test.c:234 I think it is related to the hardening option "-D_FORTIFY_SOURCE=2". What is interesting is that it builds correctly in Debian, but not Ubuntu. The issue has apparently been observed before: http://comments.gmane.org/gmane.comp.mobile.osmocom.baseband.devel/4149 If this gets fixed quickly, it might go into the next Ubuntu LTS version which has import freeze Feb 18th. Cheers, Ruben
