   3 # when using the address sanitizer, libasan must be linked/loaded first.
   4 # to make sure this happens, this script uses LD_PRELOAD to load the
   5 # library first, but only if it is necessary. If the executable is not
   6 # linked against libasan, it will be executed just as it is.
   7 #
   8 # example:
   9 #
  10 #     sanitize-wrap build/test/testrunner --gtest_shuffle
  11 #
  12
  13 # find link to libasan
  14 libasan=$(ldd $1 | grep libasan | sed 's/^[[:space:]]//' | cut -d ' ' -f1)
  15
  16 # define LD_PRELOAD if necessary
  17 if [ -n "${libasan}" ] ; then
  18         set +u
  19         if [ -n "${LD_PRELOAD}" ] ; then
  20                 export LD_PRELOAD="${libasan};${LD_PRELOAD}"
  21         else
