RedHat Linux 7.0, with kernel 2.2.17
Postgresql version 7.0.3, as well as the stock
version shipped with RedHat 7 (7.0.1???)

My app gathers a bunch of data, and then
dumps it into the database. It does not
retrieve any data from the database (other
apps do that). About 1 time out of 20, the call
to PGconnectdb fails with a segfault signal. Because
of this, I run the PGconnectdb/PGexec etc. in a
forked process. If the forked process dies because
of the signal, then I try using system("psql ....")
as described above. About 1 time out of 20 this
fails.
