A reach increase is not a bonus.
Bonus: Bonuses are numerical values that are added to checks and statistical scores. Most bonuses have a type, and as a general rule, bonuses of the same type are not cumulative (do not "stack")—only the greater bonus granted applies.
It's probably not intended to be cumulative with itself, but RAW it appears to be.
spells can't stack with themselves

Long arm, enlarge person, and the Abberant bloodrager power that gives an additional +5 ft reach all stack. Long arm and enlarge person are transmutation spell effects, so any other transmutation effects that effectively do the same specific thing (giving extra reach or increasing actual size) do not stack.

It doesn't have to be a bonus to not stack.
Generally, effects do not stack if they are from the same source (Core Rulebook page 208, Combining Magical Effects). Although temporary hit points are not a "bonus," the principle still applies.
Nothing in the Long Arm spell gives specific rules on stacking it, so it doesn't stack based on the FAQ principle.
A reach increase is not a bonus.Five is a numerical value. Reach is a statistical score.
Five is not being added to anything. Five feet is, and five feet is not a numerical value; it has dimensions of length. Hence it is not a bonus in the PF sense. If they didn't care about it, they would have dropped the word "numerical" and just said "value."
Nor is reach a statistical score, as it is not generated statistically, i.e. by rolling dice.
I don't see a difference between five feet and five temporary hit points. They're both numbers of something.
And temporary hit points are not a bonus either :-)
See the FAQ Darksol quoted.
You add the numerical value "five" to the statistical score "number of feet of reach." And whether reach is generated by rolling dice has nothing to do with it. Caster level isn't generated by rolling dice either, and a bonus to caster level is still a bonus.A reach increase is not a bonus.Five is a numerical value.

By that logic gaining 5 temporary hp would also be a bonus (you add the numerical value "five" to the statistical score "number of temporary hp"), and the FAQ says it's not.
Being a numerical value is not the same thing as containing a numerical value. That's what units and dimensions are all about.
It's still an effect, and as stated by the FAQ same effects don't generally stack.
Also stacking doesn't just refer to numbers. It just so happens that most of the time stacking bonuses is what is discussed in the forum.
If you look at the subheading "Combining Magic Effects" in the Magic chapter, it immediately goes into "stacking" which is a subsection of "Combining Magic Effects", Under the stacking subsection it goes into spells that don't have numerical value. That shows that not all stacking is number based
Now since the books says has nonnumerical effects as falling under the stacking rule, and since the FAQ calls out effects from the same source as not stacking as a general rule then Long Arm does not stack.
Sorry, I was already convinced of the non-stacking by Chess Pwn's and Darksol's posts. But someone was still disputing the point that reach increases are not a bonus, so I continued to defend it. That's all.
