Just recently I spent a lot of time tracking down a bug, that led me
deep into a third-party library. While provided as source code,
understanding why it was failing required a detailed understanding of
that library, which I don't have. I could see that the code was
generating an invalid pointer, which caused a SIGSEGV when my own code
attempted to dereference it, but I didn't understand why the generated
pointer was invalid.
When I contacted the third-party help desk, they were quite willing to
help. However, getting my example code (which I simplified as much as
possible - which wasn't anywhere near as much as I'd have liked) running
on the their system required installing several other third-party
libraries (every attempt I made to remove the dependence on one of those
libraries caused the symptoms to disappear) which they were unfamiliar
with. In the end, they found a fix that made their copy of my simplified
example work - on their system. The same fix did NOT make my copy of the
code work on my system. Security restrictions prevented us from setting
up remote access to each other's systems, and travel budget restrictions
prevented either of us from physically visiting the other company's
offices. Very frustrating.

Finding it can be fun; looking for it is often very far from fun,
particularly with SIGSEGV problems.
