Subject: Use std::string in rust_get_disr_info
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d93f4d96bb0fb307db9e2dade38ddb3c6bc469ca;p=binutils-gdb.git

Use std::string in rust_get_disr_info

This changes rust_get_disr_info to use std::string in one more spot,
avoiding a memory leak.

	* rust-lang.c (rust_get_disr_info): Use std::string in one more
	spot.
