Hi all!
Building the linux kernel, as well as doing a"make allyesconfig"
on a fresh checkout of linux HEAD results in the same Bus Error in
fixdep (details below). This is a i5 box running 32bit Ubuntu Lucid
with plenty of (free) RAM. Haven't found any hints to what might be
wrong on scanning over the web archives.
Regards
Christoph

Sorry for the noise Looks like something very odd is happening here. Seems like stat is giving us the wrong size. As seen below, ls reports the file size to be 5247 whereas st.stat indicates a size substantially larger than that.

[Context to new readers: Ben experience that fixdep (part of kbuild) exists with an error during kernel compilations. This is now tracked down to fstat() returning EINVAL. Due to missing error checks in fixdep.c this has been a long journey to reach this far. ] I looked briefly at the fstat implmnetation in the kernel and this did not give me any hints. I therefore changed to subject to attrack attention of more readers. Can you supply us with a bit more information about your system: - filesystem (as fstat seems to reach filesystem specific code) - glibc version - box (architecture + 32 or 64 bit kernel) - do you see other things misbehave or is this only a kernel build thing If you have provided this info in the past I have missed it.

You could try to print out the filename if fstat fails. If this happens while accessing the same file then try to check if this file has any special permissions / security settings.
