This suggests:
Compiling the C-parser using a C++ compiler
An effort is made to make the C-parser compilable using a C++
standard conforming compiler, as long as the semantic and location
types (if used) are POD's. This support may be dropped in future
Bison versions.
Hans Aberg
will typically
leak parser stack memory (except when the initial static stack array
is used), but this is expected. A section on the C++ parser will give
hints of using the C++ parser for proper C++ support, so one does not
need direct users to that here.
