It looks like invalid conversion of some numeric type to a (big)float.

I don't think the length of the expression has anything to do with
your problem. In fact, I routinely (un)archive much bigger expressions
(from ~100 Mb to 2 Gb) without any problems.

Could you please insert the following code into your program

#include <cln/cln.h>
#include <cstdlib>
#include <execinfo.h>

namespace cln 
	void cl_abort()
		static const unsigned max_frames = 64;
		void* frames[max_frames];
		const unsigned actual_frames = ::backtrace(frames, max_frames);
		::backtrace_symbols_fd(frames, actual_frames, 1);

and post the output? 

Best regards,
