Comment (by leif):
For the record:
With FSF GCC 4.7.2, for me R still fails to build '''without LTO''' (i.e.,
with `-O3`), while it ''does'' build with `-O3 -flto` (which isn' t
''that'' surprising, but at least funny regarding this ticket).
Presumably some GCC optimizer bug, but hard to track down as R segfaults
while byte-compiling. (This happens on Linux x86 and x86_64.)
