Glibc now defines PTRACE_GET_THREAD_AREA as an enum value. Trying to define our
own will result in an error:
../../third_party/crashpad/crashpad/compat/linux/sys/ptrace.h:25:35: error: redefinition of 'PTRACE_GET_THREAD_AREA' as different kind of symbol
static constexpr __ptrace_request PTRACE_GET_THREAD_AREA =
^
../../build/linux/debian_sid_amd64-sysroot/usr/include/x86_64-linux-gnu/sys/ptrace.h:110:3: note: previous definition is here
PTRACE_GET_THREAD_AREA = 25,
However, glibc also defines a new macro for the corresponding value, so it's
possible to detect this case:
----- ptrace.h -----
/* Get a TLS entry in the GDT. */
PTRACE_GET_THREAD_AREA = 25,
#define PT_GET_THREAD_AREA PTRACE_GET_THREAD_AREA
----- ptrace.h -----
This CL prevents defining our own PTRACE_GET_THREAD_AREA when PT_GET_THREAD_AREA
is defined.
