Subject: [Bug gdb/11786] New: PIE support may not work for some PIEs
Date: Fri, 02 Jul 2010 17:14:00 -0000	[thread overview]
Message-ID: <20100702171412.11786.jan.kratochvil@redhat.com> (raw)

PIE support update going to be checked-in for gdb-7.2:
http://sourceware.org/ml/gdb-patches/2010-06/msg00231.html

assumes in svr4_exec_displacement just P_VADDR and P_PADDR get displaced.
prelink sources contains adjust_dso() which may in some cases relocated
also/only P_OFFSET, P_FILESZ and/or P_MEMSZ.

This would disable the PIE adjustment in GDB making it fail on such PIE
inferior.  I am currently not aware of such sample program.
