assembly causing the abort

this can still be reproduced using mono's master on opensuse 11.3 x86

Compilation of System.Xml.DTDReader:CompileDeclaration () failed with exception
'Error verifying System.Xml.DTDReader:CompileDeclaration (): Invalid branch
target: Invalid instruction target 123e':
* Assertion: should not be reached at metadata.c:3749

Program received signal SIGABRT, Aborted.
