Olaf, Thank you for your time.
This are the last lines of the configure output. I am compiling with no flags.

 Build Octave GUI:                   yes
  JIT compiler for loops:             no
  Build Java interface:               yes
  Do internal array bounds checking:  no
  Use octave_allocator:               no
  Build static libraries:             no
  Build shared libraries:             yes
  Dynamic Linking:                    yes (dlopen)
  Include support for GNU readline:   yes
  64-bit array dims and indexing:     no

I was executing Octave without the GUI. I can install the control
package without crash, s yes, I believe is only with the struct
package. Other packages install well also, geometry, io, general,
signal, etc...

There are two files cell2fields.oct
/home/juanpi/.octave/struct-1.0.10/x86_64-pc-linux-gnu-api-v48+/cell2fields.oct
(35K, 21. January)
/home/juanpi/.octave/struct-1.0.10/x86_64-unknown-linux-gnu-api-v49+/cell2fields.oct
