1. attempting to resume execution on a core/minidump target (process continue)
reports an error (good) but it still changes the process state to running (bad)
resulting in a inconsistent debugger overall state:
(lldb) target create --core "core"
Core file '/usr/local/google/home/mosescu/work/crash/lldb/linux-joshua/core'
(x86_64) was loaded.
(lldb) c
error: Failed to resume process: error: elf-core does not support resuming
processes.
(lldb) bt
error: invalid thread
2. "thread info" hits an access violation:
(lldb) thread info
Stack dump:
0. HandleCommand(command = "thread info")
Segmentation fault (core dumped)
3. step commands silently fail on core/minidumps
4. quit will incorrectly warn when debugging core dumps (minidumps ok in this
case)
(lldb) target create --core "core"
Core file '/usr/local/google/home/mosescu/work/crash/lldb/linux-joshua/core'
(x86_64) was loaded.
(lldb) q
Quitting LLDB will kill one or more processes. Do you really want to proceed:
