Package: fakeroot

Severity: normal

Dear Maintainer,
I'm trying to track down an intermittent failure that originally presented like
this:
dh_md5sums
dh_builddeb -- -Znone
dpkg-deb: building package `mercury-main-4604p00p1099' in
`../mercury-main-4604p00p1099_14.1.4604.00.1099_amd64.deb'.

/usr/bin/fakeroot: line 1: kill: (6633) - No such process
dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2
I've got fakeroot now lashed up to run with debugging.
Now the presentation is like this:

The r=22, EINTR=4 line is telling me that whatever last set errno had got
EINVAL:
/usr/include/asm-generic/errno-base.h:#define EINVAL 22
/* Invalid argument */
I notice above that, even though msgrcv failed, faked called process stat
with the same arguments as given in the previous message.
The indentation of the source suggests that this was not the author's intent.
It seems unlikely to be correct.
Seeing this seeming bug still present in:
https://anonscm.debian.org/cgit/users/clint/fakeroot.git/tree/faked.c
I enclose a patch to address that.
I don't know at this juncture whether it fixes my original problem.
I doubt it but fingers crossed.
