I just took a look at adding gssapi build support on solaris (solaris
10/x86_64, sun studio 10, 64bit build) which seemed easy enough by
educating configure to look for -lgss but while it compiles just fine
the resulting tree will not be able to complete a make check due to
psql(!) segfaulting as soon as it tries to connect to the backend.
the backtrace looks similiar to:

ideas ?

Do you use also 64bit psql? Can you send me your ./configure setup? However, I see there potential integer overflow, because len is size_t and conn->outMsgEnd is defined as int.
