[lldb-dev] lldb-114: initial process state wasn't stopped

[Filipe Cabecinhas]

Hi all, 

I have some more information. It seems the problem may be with debugserver, somewhere.

When running a program with Apple's latest lldb (from the command line tools package, for Xcode 4.3), I get:
-----------------------------------------------

[~]% xcodebuild -version
Xcode 4.3
Build version 4E109
[~]% lldb --version
LLDB-112


[~]% lldb ./tests
(lldb) log enable gdb-remote all
(lldb) run



(snip)

<lldb.process.gdb-remote.async> GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse () sending continue packet: vAttach;221f
<lldb.process.gdb-remote.async> send packet: $vAttach;221f#00
<lldb.process.gdb-remote.async> GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse () WaitForPacket(vAttach;221f)
<lldb.process.gdb-remote.async> size_t GDBRemoteCommunication::WaitForPacketWithTimeoutMicroSecondsNoLock(StringExtractorGDBRemote &, uint32_t): Read (buffer, (sizeof(buffer), timeout_usec = 0xffffffff, status = success, error = (null)) => bytes_read = 270
<lldb.process.gdb-remote.async> read packet: $T11thread:1f03;qaddr:a0;02:0000000000000000;03:0000000000000000;04:0000000000000000;05:0000000000000000;06:0000000000000000;07:e0f6bf5fff7f0000;08:0000000000000000;09:0000000000000000;10:2810c05fff7f0000;11:0002000000000000;metype:5;mecount:2;medata:10003;medata:11;#00



-----------------------------------------------

With the lldb I built, I get:
-----------------------------------------------

[~]% ./dev/lldb/build/Debug/lldb --version
LLDB-115


[~]% ./dev/lldb/build/Debug/lldb ./tests
(lldb) log enable gdb-remote all
(lldb) run



(snip)

<lldb.process.gdb-remote.async> GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse () sending continue packet: vAttach;2265
<lldb.process.gdb-remote.async> send packet: $vAttach;2265#00
<lldb.process.gdb-remote.async> GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse () WaitForPacket(vAttach;2265)
<lldb.process.gdb-remote.async> size_t GDBRemoteCommunication::WaitForPacketWithTimeoutMicroSecondsNoLock(StringExtractorGDBRemote &, uint32_t): Read (buffer, (sizeof(buffer), timeout_usec = 0xffffffff, status = success, error = (null)) => bytes_read = 7
<lldb.process.gdb-remote.async> read packet: $E01#00
<lldb.process.gdb-remote.async> GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse () got packet: E01
<lldb.process.gdb-remote.async> GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse () => invalid


-----------------------------------------------


Codesign seems to say it's okay:

./dev/lldb/tools/debugserver/build/Debug/debugserver: valid on disk

-----------------------------------------------


Any clues on what's happening? I will now try to debug debug server and see where the problem may be, but this may be a known issue.

Regards,
