> This is the release of crash gcore command, version 1.2.2.
>
> ChangeLog:
>
> - Now gcore collects and writes ELF note segments in O(1) memory
> consumption with regard to the number of threads. The implementation
> so far had created ELF note segments for all the threads as a list
> at the same time, and so memory consumption had grown in proportion
> to the number of threads. In contrast, new implementation writes
> ELF note segments one by one. Without this change, gcore could fail
> abnormally if specified process consists of threads more than tens of
> thousands, with the message: "gcore: cannot allocate any more memory!".

>
> - Fix the address of vdso virtual address in x86_64 compat mode by using
> fixed VDSO_HIGH_BASE, not by vma->vm_mm->context.vdso. Without this
> fix, access to vdso page fails in x86_64 compat mode and vdso page
> fails to be collected in generated process core dump.

> - Tested on RHEL5.10.
