Apparently this is caused by generated code in lazy_lang_decl storing pointers to GCC inline functions on the heap, which then get called later in ResolveTreeNode, when they are invalid.

Not that I have any strong opinions on this, but I was thinking "not using nested functions" was a reasonable alternate solution. :-)

It's reasonable, but it's much easier with nested functions. If one starts inlining what's currently nested functions then convert_tree gets a lot more complicated. I tried that approach and it was messy, the generated code looked uglier and I couldn't bother to rewriting large parts of convert_tree js once I realized how much simpler nested functions are. Personally, I think nested functions should be part of the C/C++ standards, as they allow for much more concise code.
