title="RESOLVED FIXED - lldb assertion "Architecture or OS not supported" when loading Ubuntu core dump"
href="show_bug.cgi?id=30485">https://llvm.org/bugs/show_bug.cgi?id=30485</a>.
On RHEL6,7 we've no any of /lib/{x86_64,i386}-linux-gnu multilib path. Then
solution proposed here <a href="https://reviews.llvm.org/D25179">https://reviews.llvm.org/D25179</a> is only for
Ubuntu/Debian system and does not touch RedHat Linux.
The core dump was produced by an Red Hat Enterprise Linux Server release 7.2
(Maipo) (OS version:3.10.0-327.el7.x86_64).
Command used to launch lldb:
vladimirg@test> ~/opensource/build/bin/lldb ~/sandbox/coredump --core
coredump-27248.core
(lldb) target create "/export/home/vladimirg/sandbox/coredump" --core
"coredump-27248.core"
lldb:
/export/home/vladimirg/opensource/llvm/tools/lldb/source/Plugins/Process/elf-core/ThreadElfCore.cpp:145:
virtual RegisterContextSP
ThreadElfCore::CreateRegisterContextForFrame(lldb_private::StackFrame *):
Assertion `false && "Architecture or OS not supported"' failed.
Aborted (core dumped)
Notes from coredump:

I'll provide coredump and binary if needed.
I think we should pay attention on this bug because it really blocks usage of
lldb on RHEL.</pre>
