Steps to reproduce

I run graphviz as static libraries. I call In order to circumvent #1520 I call text font_dict_open after calling gvNEWcontext.

GVC_t * gvc =  gvNEWcontext(&lt_preloaded_symbols[0], 5);
gvAddLibrary(gvc, &gvplugin_dot_layout_LTX_library);
gvAddLibrary(gvc, &gvplugin_neato_layout_LTX_library);
gvAddLibrary(gvc, &gvplugin_quartz_LTX_library);
textfont_dict_open(gvc);  // this is a workaround due to https://gitlab.com/graphviz/graphviz/issues/1520

Expected Behaviour

library properly initiated - like it used to.

Actual Behaviour

The code seem to fail in textfont_freef - which looks harmless to me:

static void textfont_freef(Dt_t* dt, void* obj, Dtdisc_t* disc)
{
    textfont_t *f = (textfont_t*)obj;

    if (f->name) free(f->name);
    if (f->color) free(f->color);
    free(f);
}

Any ideas? Should it even be called?

OS Version

MacOS Big Sur 11.1. The problem only occurs for x86_64 architecture and not on the new arm64 - which makes this really odd. I did work previously, so it seems to be something related to Big Sur.

Graphviz Version

graphviz-2.44.1
