After fork, vgdb activity is polled according to the nr of bbs done :
|
||
|
|
once the nr of bbs done reaches the next vgdb poll, a check for vgdb
|
||
|
|
activity is done.
|
||
|
|
This might lead to the activation of gdbserver after fork.
|
||
|
|
Such poll is however not expected, unless the children is
|
||
|
|
to be trace.
|
||
|
|
This spurious poll in the forked child can cause failures
|
||
|
|
depending on the nr of bbs done before the fork, and the
|
||
|
|
nr of bbs done between the fork and the exec.
|
||
|
|
|
||
|
|
=> disable vgdb poll in the child in the cleanup after fork
|
||
|
|
in the child, unless the children have to be traced.
