[oe-users] modphp SEGV problem

[Harley Privitera]

Hi,

apache2-2.2.3-r5
modphp-5.1.6-r2

I'm trying to build an OE image for a device that uses apache2/modphp to
interact with an operator and I've run into a nasty problem trying to
get modphp to work; whenever I start apache2 with -D PHP5 and
subsequently try to access any files (.html, .php) on the OE system I
get the following SEGV in modphp:

#7  0x00000000 in ?? ()

If I enable and subsequently access /server-info like this:

<Location /server-info>
SetHandler server-info
</Location>

all is well; no SEGV, just the expected response from apache. If I start
apache2 without -D PHP5, everything works, but (obviously) .php files
are not interpreted, just shipped out as-is.

I can provide more info if needed; has anyone else run into this
problem?

TIA,
