Both files need
s/pthread tid;/pthread_t tid;/

For the first program I get no abort:

Thread created
In ThreadRun
In Some3rdPartyFunction
Cancelling Thread
Joining cancelled thread
Rethrowing abi::_forced_unwind
Returning from main

Did you mean to put an empty exception specification on the
Some3rdPartyFunction?

For the second I see an abort

Thread created
In ThreadRun
Handling int exception

terminate called after throwing an instance of 'int'

It won't change the behaviour, but any reason you don't use these
commands instead?

g++ -g bug1.cpp -o bug1 -pthread
g++ -g bug2.cpp -o bug2 -pthread

i.e. compile with the g++ driver so libstdc++ is linked in
automatically, and use -pthread so _REENTRANT is defined, as well as
linking to libpthread.
