Description

DCMTK on Linux crashes in select() when handling more than 1024 parallel network connections.
This is a well-known limitation of access(), and documented here: https://access.redhat.com/solutions/488623
The solution is to use poll() instead of select().

Attached a patch and a test program that demonstrates the crash.

Report and patch submitted by Michael Craggs <>.
