I've sent a patch https://cygwin.com/pipermail/cygwin-patches/2025q2/013726.html for review. Now I get the correct error message: 0 [main] rustc 1569 child_info_fork::abort: unable to remap \??\V:\rust\rustc-nightly-src\build-MSYS\x86_64-pc-cygwin\stage0-rustc\release\deps\tracing_attributes-0e8ab81319ad49f1.dll (using V:\rust\rustc-nightly-src\build-MSYS\x86_64-pc-cygwin\stage0-rustc\release\deps\tracing_attributes-0e8ab81319ad49f1.dll) to same address as parent (0x2090000) - try running rebaseall Ultimately, playing whack-a-mole in a 64-bit address space hoping that the DLL will load in the same place as the parent is an exercise in futility, especially in only 6 attempts. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
