Public bug reported:
Hi, the following program, call it `test_svd.m`, never finishes, but
instead runs the `svd()` line forever:
```
load a.mat
[U,S,V] = svd(A);
disp('done');
```
This is with version 5.2.0-1 in the ubuntu focal repository for amd64.
I have also tested on the same hardware in a chroot with debian testing
with octave 5.2.0-1 and this program finishes almost instantaneously, as
I would expect. So there seems to be a problem specific to the Ubuntu
Focal build.
Using ldd, I see octave is linked to the same libraries in debian
testing and ubuntu focal.
If I delete one row from the a.mat file, so that it is 91 rows instead
of 92 rows, the octave version in ubuntu focal finishes almost
instantaneously.
