--- Comment #6 from Rainer Orth <ro at gcc dot gnu.org> ---
I've run the gcc.dg/ubsan/pointer-counted-by-bounds-124230.c test manually:

/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/ubsan/pointer-counted-by-bounds-124230.c:55:23:
runtime error: index 10 out of bounds for type 'int [*]'
Bus Error                 
LD_LIBRARY_PATH=../../../sparc-sun-solaris2.11/libsanitizer/ubsan/.libs
./pointer-counted-by-bounds-124230.exe

truss shows this is an unaligned access which cannot work on a strict-alignment
target like SPARC:

    Incurred fault #5, FLTACCESS  %pc = 0x0001125C
      siginfo: SIGBUS BUS_ADRALN addr=0x00024EB2

I wonder why it shouldn't be possible to find an appropriate SPARC system
inside Oracle.  Even if so, there's always the cfarm: cfarm216 is a
Solaris/SPARC
system...
