cmake 3.16.0: does not build on PPC Mac OS X 10.5.8, "Bus Error"

[timishimuni]

Description

Building cmake fails with an apparent bus error at:

:info:configure cmake(21293) malloc: *** error for object 0xa01be3dc: Non-aligned pointer being freed
:info:configure *** set a breakpoint in malloc_error_break to debug

Environment

Power Mac G5 running OS X 10.5.8, 8G RAM, Xcode 3.1.4 From the top of the build log:

:debug:sysinfo Mac OS X 10.5 (darwin/9.8.0) arch powerpc
:debug:sysinfo MacPorts 2.6.2
:debug:sysinfo Xcode 3.1.4
:debug:sysinfo SDK 10.5
:debug:sysinfo MACOSX_DEPLOYMENT_TARGET: 10.5

Log

More context from the end of /opt/local/var/macports/logs/_opt_..._ports_devel_cmake/cmake/main.log:

:info:configure ld: warning: direct access in TargetPolicyNode::Evaluate(std::vector<std::basic_string<char,std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > const&, cmGeneratorExpressionContext*, GeneratorExpressionContent const*, cmGeneratorExpressionDAGChecker*) const to global weak symbol TargetPolicyNode::Evaluate(std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>,
 std::allocator<char> > > > const&, cmGeneratorExpressionContext*, GeneratorExpressionContent const*, cmGeneratorExpressionDAGChecker*) const means the weak symbol cannot be overriden at runtime. This was likely caused by different translation units being compiled with different visiblity settings.
