w.r.t. thread safety - I think what you want is a "pure parser".  this is a 
bison option.

well, that comment was initially a joke, sorry if it didn't seem that way.  

On a more serious note, my project is ~200 C++ classes, and I talk to flex and 
bison in C.  The concerns you express have nothing to do with C++, but rather 
the code that flex and bison generate.  C++ code is not magically thread safe.  
Just as an aside, it has been my experience, that C++ support for flex and 
bison is/was an afterthought, and I have found it easier to use the C than the 
C++.  YMMV.
