iOS app crash with EXC_BAD_ACCESS

My app is crashing specifically in 8.0 and 8.0.2 OS version.Below is the crash logs.From the crash logs, it’s understood that some font rendering is screwed up, but still not able to figure out the exact reason.Anyone else faced the same issue?

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Subtype: KERN_PROTECTION_FAILURE at 0x000000010000000c
