I do see a problem. The method stringConcatenateReverse$SlShared$V in srfi13.class has
the following:
Attribute "LocalVariableTable", length:92, count: 9
slot#0: name: string-list, type: java.lang.Object (pc: 0 length: 662)
slot#1: name: maybe-final+end, type: gnu.lists.LList (pc: 0 length: 662)
slot#2: name: final, type: java.lang.Object (pc: 23 length: 639)
slot#3: name: end, type: java.lang.Object (pc: 124 length: 538)
slot#4: name: len, type: java.lang.Object (pc: 300 length: 247)
slot#5: name: nzlist, type: java.lang.Object (pc: 300 length: 247)
slot#6: name: lis, type: java.lang.Object (pc: 300 length: 247)
slot#7: name: $ctx, type: gnu.mapping.CallContext (pc: 300 length: 247)
slot#7: name: slen, type: int (pc: 340 length: 67)
Notice slot 7 is used for two different variables, of different types - and their
PC ranges overlap. Hm.
