Subject: Re: [bugzilla-daemon@...nvz.org: [Bug 1801] VDSO: Not
enough room for program headers]
It appears to be a problem with the vdso link script (vdso.lds).
ld manual says it happens when SIZEOF_HEADERS is used before the actual
size of program headers is known and suggests to avoid SIZEOF_HEADERS
or to use PHDRS.
The odd thing is that (afaict) there is a PHDRS definition in the link
script.
Nevertheless, the code (bfd/elf.c) is quite obvious: the error message
means one of sections in the (loadable) segment including the file header
("text" in our case) collides with the headers.
Perhaps it would help to change SIZEOF_HEADERS to some generous hardcoded
constant (it might become necessary to increase offsets in subsequent "."
directives too).
