backtrace

After installing the Grammalecte extension, Writer crashed. This is on OS X Snow Leopard.

I'm not sure the backtrace is really useful, but it's all the OS offered.

something is throwing an exception of a type that is not allowed to be thrown
because it is not listed in the exception specification of a method:

3   libstdc++.6.dylib                   0x0096217a __cxxabiv1::__terminate(void (*)()) + 10
4   libstdc++.6.dylib                   0x009621ba __cxxabiv1::__unexpected(void (*)()) + 0
5   libstdc++.6.dylib                   0x009622b8 __gxx_exception_cleanup(_Unwind_Reason_Code, _Unwind_Exception*) + 0

9   libgcc3_uno.dylib                   0x0a7c478d privateSnippetExecutorClass + 17
10  liblnglo.dylib                      0x273c894d GrammarCheckingIterator::DequeueAndCheck() + 1837


given that there is UNO bridge code on the stack, it's probably the extension - likely implemented in a non-C++ language.

it is possible this bug causes a crash only on Mac OS X because
that is built with clang and clang is the only compiler where
the C++ exception specifications are actually enforced.

GrammarCheckingIterator::DequeueAndCheck() calls the
linguistic2::XProofreader::doProofreading UNO method
so presumably the implementation of that in the extension
throws the exception.

this is likely not-our-bug, please contact the authors of the extension.
