When i tried to execute a function in oracle 10g ,it threw me below exception and exited.
ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [ptmak()+372] [SIGSEGV] [Address not mapped to object] [0x000000010]  
Could you please advise on above exception. what was the root cause for this issue.Perhaps best bet is to migrate to 11.2 XE, if you can't workaround the issue e.g. change the application.
