Created attachment 235738 [details] Patch implementing the change. b64_pton_partial() takes a pointer to pointer and will update it while decoding. Then the caller will be able to copy the correctly decoded part, even if decoding another part yielded an error and aborted the process.
The patch fails to apply error: patch failed: include/Makefile:9 error: include/Makefile: patch does not apply
Created attachment 235756 [details] Rebased patch.
