Package: libboost-dev
Version: 1.33.1-9
Severity: important
File: /usr/include/boost/detail/sp_counted_base_gcc_ppc.hpp
Tags: patch

Several functions in sp_counted_base_gcc_{ppc,ia64}.hpp specify their
read-write *pw argument only as an output operand to their inline
assembly code, potentially running afoul of gcc's optimizer.  (This
can definitely be a problem with GCC 4.0.1 on Mac OS X, and I know of
no reason it wouldn't also affect 4.1.1 on Linux.)


has more details, and Boost's upstream developers committed fixes last


This could conceivably be the root cause of #404616.
