Note it is not actually x00 that fails. If you look carefully at shared/noninteractive/output_tree/make_noninteractive.out you will find that the C version of x19 appears to work fine (albeit with messages about plmap missing functionality because shapelib is not installed ) but the Tcl version of x19 fails due to a segfault which virtually guarantees there is a memory management issue either in our C or Tcl version of the plmap functionality. Note memory management issues are sometimes silent (i.e., will not produce a segfault in all cases). So Tcl example 19 could segfault but not C even if the memory management issue was in our core C library and not anything to do with our Tcl binding or examples. Anyhow, This is a perfect illustration of why we should do comprehensive testing during each release cycle for all platforms accessible to us, and my public thanks to you for doing that in this Cygwin case. I am going to follow up by trying some valgrind runs on Linux for example 19 without shapelib and for both Tcl and C to see if valgrind can spot the fundamental memory management issue that is causing the segfault for your particular (Cygwin) combination of circumstances.
