* problem.
|
|
*
|
|
* When a program's coredump is generated as ELF format, a section is created
|
|
* per a vma. In ELF, the number of sections is represented in unsigned short.
|
|
* This means the number of sections should be smaller than 65535 at coredump.
|
|
* Because the kernel adds some informative sections to a image of program at
|
|
* generating coredump, we need some margin. The number of extra sections is
|
|
* 1-3 now and depends on arch. We use "5" as safe margin, here.
|
|
*
|
|
* ELF extended numbering allows more than 65535 sections, so 16-bit bound is
|
|
* not a hard limit any more. Although some userspace tools can be surprised by
|
|
* that.
