Bug ID: 49433
Summary: concurrent_events tests: wrong breakpoint hit with
multiple concurrent breakpoints
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: mgo...@gentoo.org
CC: jdevliegh...@apple.com, llvm-b...@lists.llvm.org
All of the tests involving multiple breakpoints suffer from randomly
establishing the wrong breakpoint hit count, e.g.:
FAIL: LLDB (/home/mgorny/llvm-project/build.arm64/bin/clang-aarch64) :: test
(TestConcurrentTwoBreakpointThreads.ConcurrentTwoBreakpointThreads)
======================================================================
FAIL: test (TestConcurrentTwoBreakpointThreads.ConcurrentTwoBreakpointThreads)
Test two threads that trigger a breakpoint.

breakpoint_hit_count))
AssertionError: 2 != 3 : Expected 2 breakpoint hits, but got 3
Config=aarch64-/home/mgorny/llvm-project/build.arm64/bin/clang
It seems to be a problem in lldb/lldb-server logic somewhere that needs further
debugging.
