And the answer is that this is a known bug ("rdar://problem/4057081 infinte loop in dlsym(RTLD_NEXT, ) when symbol not found.", JFYI for those with radar access).

Could it also be a reason for iODBC to malfunction in 10.4 (rdar://4069775)? The stack trace shows a lot of recursion in dlsym...

According to the developer, it only happens when there are circular dependencies with libraries. The work around is 1) remove the circular dependency, or 2) use dlsym(RTLD_DEFAULT, "xxx") instead of RTLD_NEXT.

Unfortunately, this workaround doesn't apply if one intends to use Apple's libiodbc (though, one can always revert to OpenLink's version).
