And the answer is: they don't make a difference. I patched configure.c like this: $ diff configure.c.orig configure.c 138c138 < #define TARGET_CFLAGS_ARM_ON_X86_64 "TARGET_CFLAGS=-m32 -D_FILE_OFFSET_BITS=64" --- > #define TARGET_CFLAGS_ARM_ON_X86_64 "TARGET_CFLAGS=-m32 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE" $ and built with "make target=ARM". And it fails the same way: $ ./crash --osrelease /usr/dumps/ARM/vmdump.v3 crash: compressed kdump: cannot lseek dump vmcoreinfo unknown $ ./crash --log /usr/dumps/ARM/vmdump.v3 crash: /usr/dumps/ARM/vmdump.v3: no VMCOREINFO section $ Anyway, I've got a patch that fixes things up in a much more rational manner than the first kludge/patch that I put into crash-6.1.3 for header_version 3.
