Error description
Error Message: SIGSEGV/GPF during the compilation of a method. . Stack Trace: The top of the C++ stack should have the following function: TR_ValuePropagation::mergeDefContraints The rest of the stack is unwalkable. .
Local fix
To workaround this issue, the method that was being compiled at the time of the crash should be excluded from compilation. This can be done using the following command line option: -Xjit:exclude={*<method signature>*}
Problem summary
Part of the mergeDefContraint function incorrectly attempted to reference a NULL pointer that is part of one of the internal data structures used to perform this optimization.
Problem conclusion
This defect will be fixed in: 5.0.0 SR14 6.0.1 SR4 6.0.0 SR12 7.0.0 SR3 . The function has been altered so that the the NULL pointer can no longer be dereferneced.
Temporary fix
