idb from fortran 9.0 refuses to run

idb from fortran 9.0 refuses to run

Is anyone else seeing this? I'm using Ubuntu Hoary with their most recent em64t/amd64 kernel. (2.6.10-5-amd64-xeon)

From strace I see these errors just after the child is executed to start the debugging:

ControlDefUxPtrace::starttrace::startProcess_enableChildDebug - PT_TRACE_ME failed
Failed to allow debug of self

This is the failing command:

[pid 9133] ptrace(PTRACE_TRACEME, 0, 0, 0
[pid 9129] ... rt_sigaction resumed {0xc8a370, [INT], SA_RESTART|0x4000000}, 8) = 0
[pid 9133] ... ptrace resumed ) = -1 EPERM (Operation not permitted)

idb output:

massinissa:/tmp# idb test
Linux Application Debugger for Intel EM64T-based applications, Version 9.0-11, Build 20050617
object file name: test
Error: could not start debuggee
