From: Serhei Makarov Date: Fri, 21 Jan 2022 18:21:46 -0500 Subject: gcc12 c++ compatibility re-tweak for rhel6: use function pointer instead of lambdas instead of ptr_fun<> Git-repo: git://sourceware.org/git/systemtap.git Git-commit: f199d1982ef8a6c6d5c06c082d057b8793bcc6aa References: bsc#1196583 Saving 2 lines in ltrim/rtrim is probably not a good reason to drop compatibility with the RHEL6 system compiler. Actually declaring a named function and passing the function pointer is compatible with everything.
