why dba_close() closes a persistent resource?
In comparison mysql_close() doesn't close connection opened using
mysql_pconnect() and as result ext/mysql doesn't make this problem.
BTW: ZE resources have refcount, but unfortunately it couldn't help in this
case.

The needs of resource reference counter is pointed out by Stefan Esser many
years
ago.
I'm not sure who is the right person, but I'll assign this to Dmitry for now so
that someone could take care of this.

>From what I can tell from debugging, what's happening is that on the first
>dba_popen, a dba_info structure is allocated for the first resource.
On the second dba_popen, since it's the same file, the dba_info from the first
resource is reused. I don't know if this alone is a legitimate thing to do,
because now two resources are sharing the same dba_info. At the very least, I
would think that some sort of reference counter is need in dba_info to track
how many resources are linked to it.
When the first resource is closed, the dba_info structure is free'd at
dba.c:dba_close():423. Consequently, when the second resource is referenced,
it's using an already-free'd dba_info structure, and this causes a seg fault.
If it's truly OK to have to resources reference the same dba_info structure,
one solution might be to add a reference counter to dba_info, and to set it to
1 on the initial allocation, and increment it when linking to it on subsequent
dba_popens. When closing resources, the reference counter is decremented, and
the structure is released only when the count reaches zero.
Any thoughts?

The first valgrind memcheck I ran was on the installed php, and so it's missing
some file/line# information. Here's one where I ran it on the php where I
built it; it contains complete file/line# info:
