[Octave-bug-tracker] [bug #45507] acos returns different results on big input values on gcc 4.8

[Lachlan Andrew]

Update of bug #45507 (project octave):

                  Status:                   Fixed => In Progress

Follow-up Comment #35:

Yes, the #else code also fails.

I was thinking of having an #else clause along the lines of file #37293 (i.e.,
Marco's code translated to C++).

This is marked as a regression.  I'd suggest we use the code from 3.8.2, but
that seems to be as prone to overflow as the current #else code.  (Compiling
3.8.2 fails with my version of bison, so I can't check.)

It's not clear if this remaining aspect of the bug is worth fixing.  It's up
to you.
