Log message contains unhandled format specifier

[asakovets]

Description

This is what I see in logs:

3:WARN [FIRCLSMachExceptionDispatchMessage:208] Mach exception: 0x6, count: 2, code: 0x%llx 0x%llx.

As you can see it contains unhandled format specifier: %llx. This particular message is logged in FIRCLSMachExceptionDispatchMessage which calls FIRCLSSDKLog to finally end up in FIRCLSSDKFileLog. FIRCLSSDKFileLog does manual processing of format string and as such only handles the following specifiers: %d,%u,%p,%s,%x.

Thus %llx is printed as is.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
