Summary: double free in Kaleidoscope example
Product: new-bugs
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: new bugs
AssignedTo: [email protected]

examples/Kaleidoscope/toy.cpp creates a Module and does
TheExecutionEngine = EngineBuilder(TheModule).create();
and also
ExistingModuleProvider OurModuleProvider(TheModule);
FunctionPassManager OurFPM(&OurModuleProvider);
Both of these APIs claim in their comments to take ownership of
the Module, so it appears both are attempting to delete the
same Module when the program is finished.
In an asserts build, this is diagnosed by AssertingVH with
this message:
While deleting: double (double, double)* %binary:
An asserting value handle still pointed to this value!
UNREACHABLE executed at Value.cpp:492!
Aborted
