--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-12-09 01:34:15 UTC --- > 1. plugin DSO is dlopened by linker, not GCC. Compiling it with asan may > not work correctly. linker may not find asan DSO at run-time. No this is testing the plugin to GCC and not the linker so you are wrong there. POSTSTAGE1_LDFLAGS should be used also I think or rather if you do a botostrap with a weird option you should be testing an already installed compiler instead.
