     Type:  Bugs                           |      Status:  new         
Milestone:  Boost 1.35.0                   |   Component:  foreach     
  Version:  Boost Development Trunk        |    Severity:  Problem     
 Keywords:                                 |  
-------------------------------------------+--------------------------------
 The foreach tests break the VC++2008 release compiler.

 A typical result is

 {{{

 error has occurred in the compiler.
 (compiler file 'msc1ast.cpp', line 1411)
  To work around this problem, try simplifying or changing the program near
 the locations listed above.
 Please choose the Technical Support command on the Visual C++
  Help menu, or open the Technical Support help file for more information
 Internal Compiler Error in C:\Program Files\Microsoft Visual Studio
 9.0\VC\BIN\cl.exe.  You will be prompted to send an error report to
 Microsoft later.

 }}}

 The warning relates to the following

 {{{
 inline bool set_false(bool &b) { return b = false; }

 }}}

 which can be removed by

 {{{
 inline bool set_false(bool &b) { b = false; return false; }

 }}}

 This does not remove the crash, which occurs at lines like

 {{{
     BOOST_FOREACH( foreach_value_type i, rng )

 }}}

 or

 {{{
 BOOST_FOREACH(int i, get_vector())

 }}}
