gcc 13.3.0, cross-compiling from amd64 to arm64, warns about a possibly
uninitialized variable in Logger::parseLogLevel():
src/libcamera/base/log.cpp: In static member function ‘static libcamera::LogSeverity libcamera::Logger::parseLogLevel(std::string_view)’:
../../src/libcamera/base/log.cpp:694:55: error: ‘severity’ may be used uninitialized [-Werror=maybe-uninitialized]
694 | if (ec != std::errc() || *end != '\0' || severity > LogFatal)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
src/libcamera/base/log.cpp:690:22: note: ‘severity’ was declared here
690 | unsigned int severity;
| ^~~~~~~~
This appears to be a false positive, as the std::from_chars() function
should set severity value when it returns without an error. Still, the
warning is easy to solve, so fix it by initializing the severity
variable.
