https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285811 Bug ID: 285811 Summary: Debuggers in jail can't evaluate string literals Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: arrowd@FreeBSD.org The following simple testcase fails when ran in jail, but works outside: # gdb /bin/cat (gdb) run ... ^C (gdb) print (char*)"asd" Cannot access memory at address 0x7fffffffe45f Interestingly, the address looks completely different in the prison 0: (gdb) print (char*)"asd" $2 = 0x801608028 "asd" I first thought it is a gdb-specific problem, but it seems that lldb also suffers from it. The only difference is much less clear error message: (lldb) print (char*)"asd" error: Can't evaluate the expression without a running target due to: Interpreter doesn't handle one of the expression's operands -- You are receiving this mail because: You are the assignee for the bug.home | help
