oslog segfault #1385

Open campbellcole opened 1 year ago

When running oslog, it prints out the following text:

root@Campbells-iPhone ~# oslog
Apr 17 22:05:09 Campbells-iPhone: ======
fish: Job 1, 'oslog' terminated by signal SIGSEGV (Address boundary error)

Running with LLDB exposes a call to dyld3::MachOFile::hasLoadCommand:

root@Campbells-iPhone ~# lldb oslog
(lldb) target create "oslog"

Try otool -L path/to/oslog

It should show the LC_LOAD_COMMANDs
