Re: concerns when integrating C++ code into guile?

[Ludovic Courtès]

If Scheme code calls C++ code that throws an exception, then the stack
will be unwound by libstdc++ and Guile’s ‘dynamic-wind’ handlers and
such will not run.  That’s probably the main difficulty.

Likewise when C++ code calls Scheme code.

TeXmacs and LilyPond both embed Guile in a C++ code base so their
developers probably have more insight into this.  Since these are old
projects, it could be that they don’t use C++ exceptions.

Thanks,
