Is 0x2073756c506571ab a bogus pointer, i.e. it cannot be dereferenced?
If so, you need to figure out where did it come from. It could have
come from the xmalloc call, but then why the trace around that call
are not shown in your printfs?
And what is sizeof(struct font_metrics) there? I see no printfs which
show that, so I can only guess.
