The necessary checks were implemented and the crash doesn't occur any more. They have been pushed to the main repository.

Gnuastro's algorithm to find the mode of a distribution, using a "symmetricity" parameter to see how reliable the result is.

A "Floating point exception (segfault)" error was recently found on an image through this algorithm which can be fixed with some necessary checks before doing the necessary division.
