This postgres binary apparently contains an explicit branch to
0x3fffffffff3fdc30, which is not an address reasonably expected to contain
code. (It's not a known heap, a known stack, or a CODE section from the
binary file.) This probably confirms a toolchain bug.
Would you do "git checkout 166f943" in the source directory you've been
testing, then rerun the test and post the compressed tmp_check/log directory?
I'm guessing that will show the bad branch instruction no longer present.
