Steps to Reproduce: $ gdb golang-produced binary (gdb) start (gdb) info goroutines (gdb) goroutine 4 bt
Actual results: Undefined info command: "goroutines". Try "help info".
Expected results: Loading Go Runtime support. (gdb) start [...] (gdb) info goroutines * 1 running fname=runtime.switchtoM faddr=0x437a60 &g=0xc208000120 2 runnable fname=runtime.forcegchelper faddr=0x412010 &g=0xc208000480 3 runnable fname=runtime.bgsweep faddr=0x40dcd0 &g=0xc2080005a0 4 runnable fname=runtime.runfinq faddr=0x40d3f0 &g=0xc2080006c0 (gdb) goroutine 4 bt #0 runtime.runfinq () at /usr/lib/golang/src/runtime/malloc.go:712 #1 0x0000000000439ca1 in runtime.goexit () at /usr/lib/golang/src/runtime/asm_amd64.s:2232 #2 0x0000000000000000 in ??

The Comment 2 patch is still valid for golang-1.4.x but otherwise upstream (1.5) has already implemented almost all of the fixes in last month.
The remaining tiny ones I have posted as: https://go-review.googlesource.com/#/c/5522/ https://go-review.googlesource.com/#/c/5521/
This attachment still needs to be applied even for future golang-1.5 as it is Fedora GDB specific packaging: /etc/gdbinit.d/golang.gdb
