Hi there When I run the inspect tool in boost/libs/statechart (current CVS) I always get a std::out_of_range exception: **** exception(205): std::out_of_range: basic_string::substr ******** errors detected; see standard output for details ******** I tried with vc-7_1 and mingw builds, both with the same result. Does this ring a bell or should I investigate further? Regards, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
