Hi all,
I'm actually hitting this assert now when I try debugging clang with a
sanitized lldb. Any advice appreciated!
Stop hook #1 added.
(lldb) s
* thread #1, queue = 'com.apple.main-thread', stop reason = step in
* frame #0: 0x00000001044d2268 clang-10`clang::noteBottomOfStack() at
Stack.cpp:42:8
frame #1: 0x0000000100002295 clang-10`main(argc_=64,
argv_=0x00007ffeefbff160) at driver.cpp:342:3
frame #2: 0x00007fff722ba3d5 libdyld.dylib`start + 1
Assertion failed: (!m_exe_ctx.GetTargetPtr()), function CheckRequirements, file
