#144 The test_pltcl_standard_examples target creates Unhandled exception at the end on MinGW/MSYS

[Alan W. Irwin]

On the MinGW/MSYS/Wine platform when I run the test_pltcl_standard_examples target it builds all the required dependencies then runs the examples/tcl/pltcl_standard_examples script in the build tree. That script displays many valid plots before running into an Unhandled exception near the end. If I follow up by running those script commands by hand, I can verify the Unhandled exception is generated by the exit command and not the preceding standard examples.

So this is similar to bug 139 in that the problem shows up during the exit command. However, it is also very different since this issue is for pltcl with tcldemos.tcl rather than wish with tkdemos.tcl and so far the issue only appears for the MinGW/MSYS/Wine platform. For example, I attempted to replicate the problem on Linux for both the system version of Tcl8.5 and the epa_build version of Tcl8.6, and both tests gave absolutely clean valgrind results indicating no memory management issues at all on Linux for this case (unlike bug 139 where valgrind shows a nasty memory management issue on Linux involving threads for the wish/tkdemos.tcl case).

@Arjen: To make sure this issue is not due to some Wine bug, could you please attempt to replicate the issue on MinGW/MSYS on your Microsoft Windows platform?
