[swift-users] Swift 4.0 LLDBFrontend Crash

[Edward Connell]

While trying to debug a Netlib function, LLDB is crashing

I'm not sure what this assert means.

*LLDBFrontend:
/home/buildnode/jenkins/workspace/oss-swift-4.0-package-linux-ubuntu-16_04/swift/lib/SILOptimizer/Mandatory/AccessEnforcementSelection.cpp:613:
(anonymous namespace)::SourceAccess (anonymous
namespace)::AccessEnforcementSelection::getSourceAccess(swift::SILValue):
Assertion `isa<AllocStackInst>(address) || isa<SILUndef>(address)' failed.*
*Stack dump:*
*0. While running pass #10 SILModuleTransform ""Access Enforcement
Selection"".*

It fails every time and the same way in several functions, but not all
functions.
I tried to create a simple repro with the same function signature, but I
can't get the simple case to fail.
A debug build isn't doing whole-module-optimization, so that's not it

Ideas anyone?

Who owns the LLDBFrontend?

Thanks, Ed
