 Priority:  Normal           |  Milestone:
Component:  ports            |    Version:  2.2.1
 Keywords:                   |       Port:  gcc48
-----------------------------+--------------------------------
 address sanitizer is broken with 4.8, probably because its library is not
 installed.  It works with 4.9:

 {{{
 $ cat foo.cc
 int main() {}
 $ gcc-mp-4.9 -fsanitize=address foo.cc
 $ g++-mp-4.8 -fsanitize=address foo.cc
 ld: library not found for -lasan
 collect2: error: ld returned 1 exit status
 }}}

 (C vs. C++ is irrelevant)

 Note that neither thread sanitizers work properly:

 {{{
 $ gcc-mp-4.9 -fsanitize=thread foo.cc
 Undefined symbols for architecture x86_64:
   "___tsan_init", referenced from:
       __GLOBAL__sub_I_00099_0_foo.cc in ccs9M1Tr.o

 $ gcc-mp-4.8 -fsanitize=thread foo.cc
