Subject: Huge pages and gdb
Date: Wed, 23 Mar 2011 08:45:00 -0000	[thread overview]
Message-ID: <AANLkTinK_ux8KrnavfBOovFt-nW9mjcgVoUtsJwX0U0=@mail.gmail.com> (raw)

Hi,

My application (running on RHEL 6) calls mmap() to map huge pages.
After it crashed, I opened gdb with the core file and tried to take a
look in the huge-pages buffer that was mmapped. I got the following
error:

gdb) p pool->mem
$2 = 0x7f3201400000 <Address 0x7f3201400000 out of bounds>
(gdb) p pool->mem[0]
Cannot access memory at address 0x7f3201400000

How can I solve this so I will be able to view the contents of the buffer?

Thanks,
Erez
