Source: python-librt Version: 0.7.3-1 Severity: normal Tags: ftbfs,upstream Forwarded: https://github.com/mypyc/librt/issues/26 X-Debbugs-Cc: [email protected], [email protected] User: [email protected] Usertags: sparc64
Dear Maintainer, python-librt currently fails to build on sparc64, because there is a memory alignment issue in _write_short_int. The issue was already present in previous versions, so it's also causing build errors in other packages that rely on librt (notably: mypy[2]). I tested 0.6.2, which is currently available for sparc64, but the build logs suggest that the issue was present since at least 0.3.0-1 [1]. A possible fix could be to replace the two macros _READ and _WRITE in librt_internal.c with a call to memcpy, which takes alignment into account. Under normal conditions, it also wouldn't cause any overhead, because the compiler will optimize the function all away and replace it with direct load/store instructions.
