iOS developer FutureTap reports that someone using the company’s Where To? app saw it crash on a device running iOS 5. The app, tasked with locating the closest points of interest for a user via GPS, sent a crash report to FutureTap with references to Apple's upcoming iOS.

“Just received the first iOS 5.0 crash report. MKUserLocationBreadCrumb sounds interesting,” reads a tweet fired off by FutureTap.

The crash report sent to FutureTap (pictured left) shows a clear reference to Apple’s next-gen iOS, which indicates the tech giant is testing the software for a summer unveiling.

As noted in the tweet, the crash involved MKUserLocationBreadCrumb, which is related to the maps/location functions in iOS.

Mac-centric blog 9to5mac speculates that this could mean these APIs have been modified in iOS 5.

Apple is known to be collecting anonymous traffic data to build a crowd-sourced traffic database.

The goal is to provide iPhone users with an improved traffic service in the next couple of years, Apple revealed in a Q & A on gathering user location data.

This year’s edition of Apple’s Worldwide Developers Conference is widely believed to be the time and place for the introduction of iOS 5 - the next major revision to the mobile operating system powering iPhones, iPads, and iPod touch devices alike.

Scheduled to kick off June 6, WWDC 2011 will also witness the debut of Lion, Apple’s latest desktop OS which borrows key elements from the iPad version of iOS, applying them on top of the well-established OS X architecture.

Whether it is previewed at WWDC or not, iOS 5 is rumored to be heavily focused on cloud-based and location-aware services, with a revamped MobileMe also expected as a one-more-thing announcement.

It is unclear whether Apple plans to showcase a next-generation iPhone as well, at this year’s conference.
