Linking programs on MacOS using newer XCode versions (>= 13.3) fails with an error like this: ld: section __DATA/__thread_bss has type zero-fill but non-zero file offset file '../generated/build.o' for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) Taken from https://cirrus-ci.com/task/5812771504783360?logs=build#L43
@MoonlightSentinel updated dlang/dmd pull request #13890 "[Ignore] Debug failures for OSX on Cirrus" fixing this issue: - CirrusCI: Use ldc instead of dmd for MacOs >= 12 DMD releases cannot compile for XCode >= 13.3 because of issue 22942. - Fix 22942 - Check for S_TRHEAD_LOCAL_ZEROFILL alongside S_ZEROFILL The code generated an unexpected / invalid header for the `thread_bss` section marked as `S_TRHEAD_LOCAL_ZEROFILL`. The generated object file is rejected by ld included in newer XCode versions (>= 13.3). E.g. ``` ld: section __DATA/__thread_bss has type zero-fill but non-zero file offset file '../generated/build.o' for architecture x86_64 ``` This patch changes the existing code to treat `S_TRHEAD_LOCAL_ZEROFILL` like `S_ZEROFILL` w.r.t. the section size. https://github.com/dlang/dmd/pull/13890
