No problem with write (syscall 1).
Might this have something to do with _NR_read being 0 on Linux/x86_64?

Same problem reported for gdb Ubuntu/Linaro 7.4-2012.04-0ubuntu2.1,
so this is likely not new.

    Fix PR breakpoints/16297: catch syscall with syscall 0

    Code rationale
    ==============
    by: Gabriel Krisman Bertazi

    This is a fix for bug 16297. The problem occurs when the user attempts
    to catch any syscall 0 (such as syscall read on Linux/x86_64). GDB was
    not able to catch the syscall and was missing the breakpoint.

    Now, breakpoint_hit_catch_syscall returns immediately when it finds the
    correct syscall number, avoiding a following check for the end of the
    search vector, that returns a no hit if the syscall number was zero.

    Testcase rationale
    ==================
    by: Sergio Durigan Junior

    This testcase is a little difficult to write.  By doing a quick
    inspection at the Linux source, one can see that, in many targets, the
    syscall number 0 is restart_syscall, which is forbidden to be called
    from userspace.  Therefore, on many targets, there's just no way to test
    this safely.

    My decision was to take the simpler route and just adds the "read"
    syscall on the default test.  Its number on x86_64 is zero, which is
    "good enough" since many people here do their tests on x86_64 anyway and
    it is a popular architecture.

    However, there was another little gotcha.  When using "read" passing 0
    as the third parameter (i.e., asking it to read 0 bytes), current libc
    implementations could choose not to effectively call the syscall.
    Therefore, the best solution was to create a temporary pipe, write 1
    byte into it, and then read this byte from it.
