pitrou opened a new issue, #47015: URL: https://github.com/apache/arrow/issues/47015
### Describe the bug, including details regarding any error messages, version, and platform. On various PRs, crashes [have appeared](https://github.com/apache/arrow/actions/runs/16118470582/job/45477896283?pr=47013) on the AMD64 Conda C++ AVX2 build. According to a preliminary analysis, the only relevant change is that the conda-forge package `binutils` was upgraded from 2.43 to 2.44. I could reproduce this locally using Archery: ``` archery docker run -e CLANG_TOOLS=14 -e LLVM=14 -e UBUNTU=22.04 -e ARROW_USE_LD_GOLD=OFF conda-cpp ``` Then I downgraded `binutils` to 2.43 in this Docker build, and validated that the crashes disappear. I looked into the [GNU ld changelog](https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=ld/NEWS;hb=refs/heads/binutils-2_44-branch) and nothing relevant stands out. Then I noticed that with `binutils` 2.44, conda-forge also removed the faster `ld.gold` linker. So, with `binutils` at 2.43, I disabled `ld.gold` using and rebuilt. The same crashes appeared again. Finally, I installed and used the `mold` linker again, and there were no crashes. So, for some reason, we have: * tests crash with GNU `ld` 2.43 and 2.44 * tests pass with `ld.gold` 2.43 * tests pass with `mold` 2.40.1 ### Component(s) C++, Continuous Integration -- This is an automated message from the Apache Git Service.
