Summary: If you look at the backtrace in a crash log, the last column gives the symbol name followed by an address offset, for example, "objc_msgSend + 16". This offset is in decimal, base 10. However, anyone who will actually use this information, such as to examine the disassembly of the executable code, needs this information in hexadecimal, base 16. Thus, I'm requesting that the format be changed to print the offsets in hexadecimal rather than decimal. Steps to Reproduce: Open a crash log. Read the backtrace. Expected Results: 0 libobjc.A.dylib 0x90a594c0 objc_msgSend + 0x10 Actual Results: 0 libobjc.A.dylib 0x90a594c0 objc_msgSend + 16 Regression: I believe that the offset prints in decimal in all versions of Mac OS X, including Leopard.
