The current implementation of sockaddr_storage in main/php_network.h
when an OS version is not available breaks word alignment of the
structure. This showed up when compiling php w/ Sun Workshop Pro 4 &
Forte 6 rather than gcc. A SIGBUG would occur when I was testing the
ext/ftp extension.
RFC2553's reference implementation put the max padding size at 128,
which is also the size that fixed the problem in my tests. Here is a
patch based off of today's cvs. I've also put in a check for
sockaddr.sa_len into configure.in so the implementation of
sockaddr_storage can vary. Though I'm not completely sure the padding
is always correct when sa_len is found, as I dont have access to a
system in that situation, but this is a step in the right direction if
not the fix.
Phil.
