Dear Maintainer, The package build of gcr currently fails for the sparc64 architecture due to misaligned access to 64-bit memory, as can be seen in the build log: https://buildd.debian.org/status/fetch.php?pkg=gcr&arch=sparc64&ver=3.34.0-1&stamp=1571748585&raw=0 The build errors do not directly break the build, but cause unit tests to crash with a bus error, and will likely make the resulting library unusable. The root of the problem are constructs like this, where value is a const guchar * that can have arbitrary alignment: *result = *((CK_ULONG*)value); As an easy workaround, this can be replaced by: memcpy(result, value, sizeof(CK_ULONG)); This will result in safe memory access, and is usualy optimised out by the compiler, so there is no runtime cost. I'm working on a patch that does this for all such constructs.
