I just did a clean build (debug) on Linux, and I noticed that the LLDB
tests seem to consistently get stuck:
* -- Testing:
1002 tests, 12 threads --
*
* 99%
[==-]
ETA: 00:00:01*
*lldb-Suite :: types/TestIntegerTypes.py *
At this point there are a bunch of llvm-lit processes waiting and two
suspicious LLDB unit tests:
*ProcessGdbRemoteTests
--gtest_filter=GDBRemoteCommunicationClientTest.GetMemoryRegionInfo*
*ProcessGdbRemoteTests
--gtest_filter=GDBRemoteCommunicationClientTest.GetMemoryRegionInfoInvalidResponse*
I took a quick look and they both seem to blocked on communicating with the
remote:
