Use correctly-aligned codepaths on all platforms, not just Solaris & ARM (!8) · Merge requests · libopenraw / exempi

matoro1 requested to merge matoro1/exempi:master into master Feb 10, 2024

On SPARC, and under some circumstances 32-bit ARM, unaligned accesses will always crash with SIGBUS. However, they are undefined behavior on all platforms, so it is never correct to issue unaligned accesses. UBSAN can identify this on gcc or clang. The aligned path typically uses memcpy(), which modern compilers can easily optimize away.

I discovered this issue in the test suite for python-xmp-toolkit, which uses exempi. Here's the difference in the UBSAN logs, before:
