The binaries in the install dmgs for Wireshark don't have debugging symbols, so
if, for example, you kill wireshark-bin with SIGABRT, you get

as opposed to

(note the source file and line number in stack frame item 6) which I got from
killing Wireshark run from the command line in a build tree.

This makes it harder to debug problems such as the one in bug 9582; the stack
trace in

   
http://ask.wireshark.org/questions/28244/mac-os-109-mavericks-wireshark-always-crash-right-after-i-started-the-capture

doesn't indicate where in dissect_ieee80211_common() the crash occurred.

If we run symbols on the binary from the installed app bundle we get

with no line-number symbols, but if we run it on the binary from the build tree
we get

                0x0000000100001fc0 (     0xc) capture-pcap-util-unix.c:362

with line-number symbols.

If I build a dmg from the build tree, and install from it, the debug symbols
are present in
/Applications/Wireshark.app/Contents/Resources/bin/wireshark-bin, so I'm not
sure where they're getting removed.
