> Why would this be true?  Is there a minidump specification somewhere that says that both big endian and little endian are valid byte orderings?  I would expect that being a Microsoft created format, it should always be little endian, and if there is a file in big endian we can consider it corrupt.
I didn't find anything in the MS documentation about the minidump's endianess.
I am doing this because breakpad does this too: https://chromium.googlesource.com/breakpad/breakpad/+/master/src/processor/minidump.cc#4384
