Clang fails to compile a number of files with the following warning: indirection of non-volatile null pointer will be deleted, not trap [-Wnull-dereference]. This commit qualifies the relevant pointers with 'volatile'. gdb/testsuite/ChangeLog: * gdb.base/bigcore.c (main): Use a volatile pointer when attempting to trigger a SIGSEGV. * gdb.base/gcore-relro-pie.c (break_here): Likewise. * gdb.base/gcore-tls-pie.c (break_here): Likewise. * gdb.base/savedregs.c (thrower): Likewise. * gdb.mi/mi-syn-frame.c (bar): Likewise.
