[Valgrind-users] Re: [Bug 71046] New: Unable to run CVS HEAD "Executable is mapped outside of range"

[<ar...@de...>]

I've tested this and I think it's related to a prelinked stage2 binary.

When I prelink (http://www.gentoo.org/doc/en/prelink-howto.xml) the system,
particulary /usr/lib/valgrind/stage2 (from valgrind-snapshot debian package), 
valgrind stops working.

If I undo the prelinking (prelink -u) on this file, valgrind will work again.

There may be some hardcoded address within the code of stage2 because what
prelink does is (roughly) to relocate symbols of an ELF file and hence, it 
does change the binary addresses somehow.

I don't know if this can be fixed or in the future, prelink and valgrind
cannot coexist together.

Thanks.
