Bug#1037541: libguestfs: FTBFS: supermin: error: lstat: Value too large for defined data type: /var/tmp/supermin2b73c8.tmpdir/base.d/init
[https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1037541] I think what's happening here is we are using the 31/32 bit lstat functions in OCaml: https://github.com/ocaml/ocaml/blob/3d50c168062e9fdbacf739a73738b10108ff3628/otherlibs/unix/unix.mli#L500 (I guess st_size which is signed 31 bits on armv7, but 63 bits on 64 bit platforms). We ought to be using the 64 bit version instead: https://github.com/ocaml/ocaml/blob/3d50c168062e9fdbacf739a73738b10108ff3628/otherlibs/unix/unix.mli#L544 The specific problem will be that the size of some file has grown larger than 1GB resulting in this runtime error, although that seems unusual. Now we *ought* to be using those functions already because we should always be doing: open Unix open Unix.LargeFile to use the "LargeFile" (64 bit) versions of the functions. I had a quick look through the code to see where we are using 'open Unix' without 'open Unix.LargeFile' but I couldn't find the place, leaving me confused. (Of course the other problem is that Fedora has abandoned all 32 bit platforms long ago so we never test this ...) Practically my recommendation is to exclude the whole virt stack on armv7 since it has been years since we tested it.

Bug#1037541: libguestfs: FTBFS: supermin: error: lstat: Value too large for defined data type: /var/tmp/supermin2b73c8.tmpdir/base.d/init

Likely a 32bit-arch-specific issue. My guess is that somewhere within supermin, off_t is still at a 32bit value and the filesystem image generated during the tests is larger than that. Cheers, -Hilko
