[Boost-users] another problem with crc.hpp

I'm compiling some code that uses crc.hpp. On windows (VS2003) it works
fine. On Solaris 8 (Sun Studio 8), I get the following error. (offending
code included below)

>> Assertion:  unhandled expression in abi2_mangler::entity_expression
(../lnk/v2mangler.cc, line 1584)

    while processing /.../boost/crc.hpp at line 57.

 

If I delete lines 47-58, I get the same error on line 45. If I delete
lines 41-59, I get the same error on line 39 which is a comment. A
google search turns up a thread in sun's forums dealing with a bug in
the Forte 7 compiler. However, that only showed up when compiling with
-g so I removed the -g from my compile line and still get the error. Has
anyone else seen this?

 

 

36  // workaround is to make up a dummy function argument that encodes
the template

37  // arguments.  Calls to such template functions need all their
template

38  // arguments explicitly specified.  At least one compiler that needs
this

39  // workaround also needs the default value for the dummy argument to
be

40  // specified in the definition.
