[Libpqxx-general] pqxx::connection crash under libpqxx 2.6.9 and 3.0.0, OSX Leopard

[Matthew Fanto]

I am just starting to play with libpqxx, so I am quite certain the issue is
with me and linking problems. I have tested this under both libpqxx 2.6.9
and 3.0.0 and both crash at the same point. The following code causes a
EXC_BAD_ACCESS violation under Leopard 10.5.4 and Xcode 3.0.

using namespace pqxx;

try {
 connection C;
} catch (exception& e) {
....
}

Even if I pass a connection string to connection C("dbname = foo"); I still
get a crash.

I built libpqxx from source, with ./configure && make && sudo make install

I have tried various linker settings, such as adding -lpqxx -lpq to "Other
Linker Flags" (OTHER_LDFLAGS). Or linking against shared libraries with
(/usr/local/lib/libpqxx.dylib).

The other strange thing I have notices is visibility warnings, which was
fixed by selecting "GCC_SYMBOLS_PRIVATE_EXTERN"

I am able to successfully build and run test001, test002, etc. It makes me
believe that it is a linker issue I am missing. Any help would be greatly
appreciated. I am 100% certain it's a dumb mistake on my part.
