commit 0e20d056e91b033239da0253346788bdba8098e9 Author: cypherpunks <cypherpunks@torproject.org> Date: Thu May 19 13:09:31 2016 +0000 Prevent ASAN from registering a SIGSEGV handler AddressSanitizer's (ASAN) SIGSEGV handler overrides the backtrace handler and prevents it from printing its backtrace. The output of ASAN is different from what 'bt_test.py' expects and causes backtrace test failures. The 'allow_user_segv_handler' option allows applications to set their own SIGSEGV handler but is not supported by older GCC versions. These older GCC versions do support the 'handle_segv' which prevents ASAN from setting its SIGSEGV handler. --- src/test/test_bt.sh | 1 + 1 file changed, 1 insertion(+) diff --git a/src/test/test_bt.sh b/src/test/test_bt.sh index 83fa3ff..fe17816 100755 --- a/src/test/test_bt.sh +++ b/src/test/test_bt.sh @@ -3,6 +3,7 @@ exitcode=0 +export ASAN_OPTIONS="handle_segv=0:allow_user_segv_handler=1" "${builddir:-.}/src/test/test-bt-cl" backtraces || exit $?
