------------------------------------------

             Summary: Scope Tracing: format string is not a string literal
                 Key: ASTERISK-29576
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29576
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Logging
    Affects Versions: 18.6.0, 16.20.0
         Environment: Clang 12.0.0-3 of Ubuntu 21.04
            Reporter: Alexander Traud


This issue was introduced with [GERRIT-14463|https://gerrit.asterisk.org/14463]. Why ever, the compiler Clang but not GCC is not complaining about this.

*Steps to Reproduce* (see {{contrib/scripts/install_prereq}}):
{code}
sudo apt install make clang libblocksruntime-dev pkg-config
sudo apt install libedit-dev libjansson-dev libsqlite3-dev uuid-dev libxml2-dev
CC=clang CXX=clang++ ./configure --enable-dev-mode=noisy
make
{code}
*Result*:
{code}
logger.c:2449:50: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
        ast_log_full(__LOG_TRACE, -1, NULL, 0, NULL, 0, ast_str_buffer(fmt), ap);
                                                        ^~~~~~~~~~~~~~~~~~~
{code}Unsure what to do about this. The comments on Gerrit indicate that this code snippet is still under investigation. I could disable this particular error for the file {{./main/logger.c}} in Developer Mode, in general or just for Clang. Any suggestions? Or we ignore this issue because nobody (?) is using Clang with the Developer Mode of Asterisk. Not sure.
