This is fixed in main and only happens when linking against the llvm dylib. I will try to bisect but the Beaker machine I got is pretty slow. Build lldb-14.0.0-1.el9 fixes the issue. Now lldb connects and debugs the target executable properly:
+ rpm -q --requires lldb
python3-lldb
+ grep python3-lldb
+ g++ -g test.cpp
+ lldb -b -o 'breakpoint set --file test.cpp --line 7' -o run -o 'p v' -- a.out
+ tee lldb.log
(lldb) target create "a.out"
Current executable set to '/var/tmp/tmt/run-128/tests/build-gating/discover/lldb-upstream/tests/tests/python-embedded-interpreter/a.out' (powerpc64le).
(lldb) breakpoint set --file test.cpp --line 7
Breakpoint 1: where = a.out`main + 108 at test.cpp:7:40, address = 0x0000000010000a38
(lldb) run
Process 36322 stopped
* thread #1, name = 'a.out', stop reason = breakpoint 1.1
frame #0: 0x0000000010000a38 a.out`main at test.cpp:7:40
4 main ()
5 {
6 std::vector<int> v (1, 2);
-> 7 std::vector<int>::iterator it(v.begin());
^
8 return 0;
9 }
Process 36322 launched: '/var/tmp/tmt/run-128/tests/build-gating/discover/lldb-upstream/tests/tests/python-embedded-interpreter/a.out' (powerpc64le)
(lldb) p v
(std::vector<int, std::allocator<> >) $0 = size=1 {
[0] = 2
}
++ grep -e '(std::vector<int, std::allocator<> >) $0 = size=1 {' -e '\[0\] = 2' lldb.log
++ wc -l
+ test 2 -eq 2
+ rm lldb.log

Description of problem: lldb loses connection with lldbserver when trying to run a simple program in ppc64le Version-Release number of selected component (if applicable): python-lit-13.0.1-1.el9 llvm-toolset-13.0.1-1.el9 llvm-13.0.1-1.el9 lldb-13.0.1-1.el9 compiler-rt-13.0.1-1.el9 clang-13.0.1-1.el9 lld-13.0.1-1.el9 libomp-13.0.1-1.el9 How reproducible: 100% Steps to Reproduce: $ cat test.cpp #include <stdio.h> #include <vector> int main () { std::vector<int> v (1, 2); std::vector<int>::iterator it(v.begin()); return 0; } 1. g++ -g test.cpp 2. lldb -o run -- a.out Actual results: [root@ibm-p9z-23-lp7 lldb-test]# lldb -o run -- a.out (lldb) target create "a.out" Current executable set to '/root/lldb-test/a.out' (powerpc64le). (lldb) run Process 2274151 exited with status = -1 (0xffffffff) lost connection Process 2274151 launched: '/root/lldb-test/a.out' (powerpc64le) Expected results: Successful run and "Process XXXXXXX exited with status = 0 (0x00000000)" message.
