转到工具pprof list命令会给出“语法错误：“（”意外”

Question

I've got a cpu profile file that I've been examining for a bottleneck in my code and using the commands like top10 works fine. However, when I want to look at the source code listing by typing

list Remove

Where Remove is the function I want to list, it gives the following output:

(pprof) list Remove
Total: 207 samples
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected

Any ideas?
