While experimenting with a (trivial) custom instance of Array (to determine

Error in backend: File backend.c, Line 654 (!(originalsdef->sdef_arfun ==
BEArrayUpdateFun))
clm: reading compiler result failed: No such file or directory
I get the same message, whether using clm 2.4 on Mac OS X or 2.3 on Linux.
I am alerting you to this error, as it seems to represent an undesired failure
mode. But I also wonder in particular, does the current release support
creating a custom instance of Array, and then exploiting the special updating
syntax?
No, defining custom instances of class Array is not supported.
Unfortunately the compiler does not check this, causing an error
in the backend.
Kind regards,
