I wonder if someone with better and/or more recent low level
debugging skills than I could take a quick look at this.
Jgraph appears to be getting a segfault before reaching
main(). It looks like either I'm missing something really
obvious, or there's a wider problem here.
I installed the last known working version of jgraph, and
it runs fine. I rebuilt from those sources, and it segfaults.
I rebuilt using -g and ran it under gdb, and it gets a segfault
before reaching main(). It also segfaults before reaching
main() if built from current sources, which haven't changed
substantively from the last known working sources.
Here's a log of my gdb session:
