# There seem to be a problem with unwinding of exception handling when
|
|
# the binaries are compiled with -flto. For instance in autfilt,
|
|
# argp_parse() calls the locally defined parse_opt() that calls
|
|
# remove_ap::add_ap() (in libspot). The latter may throw an
|
|
# exception, which should be caught in main(). However If autfilt is
|
|
# compiled with -flto, the exception never traverses argp. Moving
|
|
# the try/catch block inside parse_opt() also fixes this praticular
|
|
# problem, but who knows about other exceptions? So as a workaround,
|
|
# we simply disable -flto in src/bin/.
