Right, if it happens. If you deinstall the extensions and remove
the config files from the old installation, and let the new installation
do all its work of new config files and new extensions, I wouldn't
expect any httpd core dumps, though.
It's happened to me many times, but it was always due to "leftovers"
from a minor version increase via portupgrade, or the fact that I
had switched Apache from no-SSL to an SSL type, and the extensions
were compiled against the libraries for the former.
The other "gotcha" in relation to FBSD is the location of the extension
dir, and "doubling" of entries in extensions.ini, but I'm thinking a
new installation would fix that problem.
As far as PHP goes, getting rid of "short tags" in the PHP code was
all we had trouble with when migrating 4.x->5.x, other than getting
my head around new OOP paradigms....
