Re: Bug#1009712: sv: fails to control the service on Hurd

[João Pedro Malhado <phlogiston@sapo.pt>]

Hello Samuel,

As you suggested the open64() function being used seems to be that defined in
sysdeps/mach/hurd/open.c

However errnno is already 1073741902 before the function call, so does not
really change after the function call. On the other hand the variable fd that
stores the value returned from open() flips from 0 to -1. I attach a brief gdb
log.

So I don't know what to look for at the moment.

Best regards,
João
