A similar question pops up regularly, if this is the same problem, one
solution is explained at. I know that the bug description is not very
clear, but it solved my problem.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=208132

If my memory serves me right, I had to edit
/usr/src/bin/csh/config_p.h and replace on line 37:

#define VFORK

by

/* #define VFORK */
#define vfork fork

The make, make install.

Best regards,

Olivier
