We run out of stack space when garbage collecting by means of too deep
recursion (I see 99% gt_ggc_mx_lang_tree_node in the backtrace,
1% gt_ggc_mx_VEC_qualified_typedef_usage_t_gc).

The testcase is probably not easy to reduce, so I wouldn't waste my time.

A workaround is to up stack space with ulimit -s (64MB worked for me).

Note that the testcase throws errors after doing that.
