no matching function for call to 'Array<std::complex<double> >::Array(octave_idx_type&, int)'

[PhilipNienhuis]

On my system, changeset 5b263e517c95 "Remove liboctave methods and classes
deprecated for longer than 3 years." (by Carnë) gives rise to a long series
of related to (AFAICS) complex double stuff:

======================================================

"hg update" to previous cs (346b20b2c2ff "Adapt genpropdoc.m.......") and
rebuilding gets me a working ./run-octave.


My system:
Mageia-4 64 bit (just recently installed)
configure w/o any special settings (esp. no --enable-64)
AFAICS the only missing dependency noted by ./configure was fftw3.

AFAIU it looks like either the deprecated methods and classes still did
serve some purpose, or the deprecation wasn't completely replaced by other
methods/classes.
Maybe bug #43646 is also related, but I read that the OP's errors were
related to QR while on my box I don't see QR mentioned in the error
messages.
