st: Tests of overidentifying restrictions after xtivreg2

Dear Statalisters,
I have estimated the following equation by using xtivreg2, gmm function:
xtivreg2 lsalary ceodual ........ (ownexr ownex2r ownex3r L.ldiv
L.debt=lrisk ..., fe gmm cluster(id) small ffirst
The test results turn out fine. But when I continue with the xtoverid test
after the above estimation,
xtoverid, cluster(id)
the following error message appears:
xtoverid error: internal reestimation of eqn differs from original
r(198);
I read the help file of xtoverid and it is mentioned that it supports
xtivreg2. May I know what is the problem and how to fix it?
Thank you very much in advance.
Best regards,
Lim Boon Leong
