LLVM IR parse error

[ljcppp]

When I am parsing some LLVM IR code which was generated by JLang from Java code to ll.rkt, something error happens.

llvm: error: invalid field 'variables'

linkageName: "Jni_trampoline_(L)L", scope: !1, file: !1, 
line: 52, type: !5, isLocal: false, isDefinition: true,
