I looked at the CLFS build I did for our last release of 2.1.0 which  
used gcc-4.8.1 with a branch update patch right before release and  
this is my summary and the test above passed.

Although my host was a debian jessie system at the time:

Running /sources/gcc-4.8.1/gcc/testsuite/gcc.dg/asan/asan.exp ...

That test passed and the summary:

                 === g++ Summary ===

# of expected passes            52135
# of expected failures          290
# of unsupported tests          653
/sources/gcc-build/gcc/testsuite/g++/../../xg++  version 4.8.1 (GCC  
for Cross-LFS 4.8.1.20131001)

                 === gcc tests ===


Running target unix

                 === gcc Summary ===

# of expected passes            92152
# of expected failures          263
# of unsupported tests          1283
/sources/gcc-build/gcc/xgcc  version 4.8.1 (GCC for Cross-LFS  
4.8.1.20131001)


And for the LFS 7.4 test logs where Running /sources/gcc-4.8.1/gcc/ 
testsuite/gcc.dg/asan/asan.exp ...  passed:

		=== g++ tests === Running target unix

		=== g++ Summary ===

# of expected passes		54027
# of expected failures		290
# of unsupported tests		877
/sources/gcc-build/gcc/testsuite/g++/../../xg++  version 4.8.1 (GCC)

		=== gcc tests ===


Running target unix

		=== gcc Summary ===

# of expected passes		93302
# of expected failures		261
# of unsupported tests		1368
/sources/gcc-build/gcc/xgcc  version 4.8.1 (GCC)

I did have it fail back in May, but not this time around when I  
released CLFS 2.1.0.
