Comment (by teor): Replying to [comment:6 nickm]: > This seems to be compiler-dependent and library-dependent, and not have much to do with Tor's actual behavior or use of backtrace. I'm putting this in needs_information to get this information: > * Which compiler and version? Which OS and version? gcc 4.9, 5, 6 on macOS 10.11 - 10.12 on x86_64 (clang and gcc i386 are not affected) > * Is this or is this not a regression? Unlikely, because the default compiler on macOS has been clang for ages. > * What is the output in each case? {{{ BAD Feb 24 13:20:34.917 [err] tor_assertion_failed_(): Bug: src/test/test_bt_cl.c:43: crash: Assertion 1 == 0 failed; aborting.
