Sure. No trouble. Check out PCCTS (ANTLR parser generator, DLG lexer
generator, and SORCERER tree-parser generator). In C++ mode, all
parsers/lexers are completely self-contained objects that should be
thread safe (e.g., there are no globals to get clobbered). I regularly
create parsers as local variables in my grammar rules to handle include
files and such.


See ftp://ftp.parr-research.com/pub/pccts/* and comp.compilers.tools.pccts
for more info.


BTW, I believe YACC++ can do the same thing...very OO (costs though).
