Pau Espin Pedrol pespin at sysmocom.deHi, Some of you may have noticed that I have been lately fixing compilation warnings + enabling -Wall and -Werror on jenkins build for several osmocom libraries. While doing so, I noticed that the following lines trying to enable AddressSanitizer support are actually failing when building with the FreeBSD jenkins slave, probably due to it using some other shell without bash support: ./configure: CFLAGS+= -fsanitize=address -fsanitize=undefined: not found ./configure: CPPFLAGS+= -fsanitize=address -fsanitize=undefined: not found The source lines are: CFLAGS+=" -fsanitize=address -fsanitize=undefined" CPPFLAGS+=" -fsanitize=address -fsanitize=undefined" After changing them to support sh and submitting the change in gerrit [1], AddressSanitizer was enabled in FreeBSD for first time, but I started getting lots of link issues with AdressSanitizer (asan) related symbols. I read in several places that there seems to be a known issue with FreeBSD 10.3 and clang-3.4.1 (what we are using) regarding use of AddressSanitizer [2, 3]. I then tried configuring CC in the jenkins slave to use clang37 instead of cc (clang-3.4.1), and then the linking issue seems to be solved, but again a new compiler bug related to usage of __builtin_cpu_supports shows up, preventing compilation of libosmocore [4]. I think the best solution is to disable explicitly AddressSanitizer in contrib/jenkins.sh when running from FreeBSD, so the behaviour is actually the same as before, in which it was implicitly not enabled due to a syntax error. Once we move to FreeBSD11 and clang-3.8 we can try enabling it again. If nobody comes with a better solution or is against this, I will proceed to do so during next hours/days.
