Bug ID: 24530
Summary: LLDB can miss inferior SIGSTOP and SIGINT under some
circumstances
Product: lldb
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: lab...@google.com
CC: llvm-b...@lists.llvm.org
Classification: Unclassified
This happens when the inferior gets a signal at the same time we are trying to
interrupt it. If the signal is SIGSTOP or SIGINT, the interrupt machinery in
GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse can mistake
the real signal stop for the maintenance stop and resume the process
incorrectly. RaiseTestCase.restart_bug_test reproduces this behavior. The bug
affect all targets which use the remote stub.
