Greetings,
gdb.base/foll-fork.exp is failing for me on Linux with VDSO:
(gdb) r
Catchpoint 1 (forked process 24244), 0xffffe410 in __kernel_vsyscall ()
(gdb) bt
#0 0xffffe410 in __kernel_vsyscall ()
#1 0x4dc3a456 in fork () from /lib/tls/i686/cmov/libc.so.6
#2 0x080483df in main () at ../../../src/gdb/testsuite/gdb.base/foll-fork.c:23
(gdb)
Attached patch fixes that.
Ok to commit?
