Re: GDB problem on Debian ia64

Émeric, Patrick,

thanks for the valuable info.

Patrick / Stephan,

I fear I was unclear.

I don't think that the GDB problem is related to the missing accept4
syscall. It's only that I experienced this GDB problem back in
February, in the same timeframe than the udev issue that was in the
end caused by the missing accept4 syscall.

Sorry for the confusion.

Stephan / Émeric,

I compiled Linux 3.7.0-rc3 and installed GDB 7.4.1-3 (sid) -- doing "gdb
man" hits a breakpoint at 0x0000000000000000 just like he described. I'm not
sure if it is a kernel thing -- I just compiled mine from Linus's git
repository last night. I don't mind doing a little spelunking into the
kernel code though -- you think it might have to do with the accept4()
syscall? Any other hints? (For a second, I was about to write, "let's just
run GDB in GDB and then we can..." -- doh).

Hi Stephan,

This vaguely reminds me something... Yes, back in February, while I
was still chasing what in the end was missing accept4 syscall, I
experienced a similar issue
(http://lists.debian.org/debian-ia64/2012/01/msg00016.html). From this
post, this was with linux-image-3.1.0-1-mckinley_3.1.8-2_ia64.deb
Debian kernel. I don't remember the GDB version though (probably the
one in Testing repository at this time) and I no more have the GDB
core dump I'm talking about in this post :-(

Kernel image and GDB currently in Testing repository
(linux-image-mckinley-3.2+45 and gdb-7.4.1-3) work fine as I've just
updated bug #642750
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=642750) using such a
configuration. Looking at my aptitude logs, gdb-7.4.1-1.1 was working
fine too.

Hope this helps,

     Émeric
