PHP 5.5 upon login, Drupal.services.call - onload - SyntaxError: JSON Parse error: Unexpected EOF [#2469869]

I'm getting the following errors when attempting to log in through Drupalgap in the iOS simulator:

First, I get the following resource errors in the Safari debugger. However, these do not affect operation as far as I can tell (just noting them in order to be complete).

[Error] Failed to load resource: The requested URL was not found on this server. (jquery.mobile-1.4.2.min.map, line 0)
[Error] Failed to load resource: The requested URL was not found on this server. (jquery.min.map, line 0)

Then I log in to the site via the app with a valid username and password.

[Log] POST: http://myserver.com/?q=drupalgap/user/login.json (console-via-logger.js, line 173)
[Log] 200 - OK (console-via-logger.js, line 173)
[Log] POST (ERROR): http://myserver.com/?q=drupalgap/user/login.json - 200 - OK (console-via-logger.js, line 173)

But then I get this error message (Drupal.services.call - onload - SyntaxError: JSON Parse error: Unexpected EOF)

Drupal.services.call - onload - SyntaxError: JSON Parse error: Unexpected EOF

I didn't experience this problem before, so I tried to roll back a couple weeks in version control, but I still had the same problem after clearing caches and rebuilding. Any pointers about where to look further for the cause of this problem would be much appreciated.

Have you tried updating to the development snapshot of jDrupal? https://easystreet3.com/jDrupal/download

I believe this me be related to this commit: https://github.com/easystreet3/jDrupal/commit/add9bb12b378ac5e691f95dd55...

I downloaded the dev version of jDrupal-min, placed it in my www directory, changed the link in index.html to point to it, rebuilt my app, reset the iOS simulator, and then tried to test it again-- unfortunately, I received the same error.

Sorry, try the non minified version of jDrupal (the minified dev snapshot can be behind sometimes).

Very strange how it says a POST error with a 200 OK.

Ok, so I downloaded the non-minified dev version of jDrupal, placed it in my www directory, changed the link in index.html to point to it, rebuilt my app, reset the iOS simulator, and then tried to test it again-- and unfortunately, I received the same error.

BUT, then I remembered a couple weeks ago I had upgraded my dev server from PHP 5.3 to 5.5-- and so I switched it back from 5.5 to 5.3, reset everything, and tried again-- this time, I was able to log in without any problem.

So, this is no longer an urgent request (as I can just roll back to PHP 5.3), but at some point it would be nice to figure out what is behind the incompatibility with 5.5.
