Dear Maintainer, I guess this crash might be a stack exhaustion.
Given the function treescan in dirs.c would allocate for locname 4096 bytes, and this function is called recursively, we would fill up a stack of 8MB, which 'ulimit -s' shows at my system as default. Therefore another workaround might be to try to increase the stack size e.g. by "ulimit -s 16384". (Have not tested it.) And a possible software change could be to allocate the memory for locname from heap by e.g. malloc instead of stack. (If such deep hierarchies are being tried to support ...)
