I finally got it working on this box. The only difference between the boxen where Inkscape was running correctly and this one where it was not, is that this one has GCC3.4.1 on it. I built Inkscape on this box with GCC3.3 to test, and it worked.
Maybe there is a quirk with vector indexing & unsigned ints on the current g++/stl? I traced my problem to line 190 of ShapeSweep.cpp, where an infinite loop was in progress. Having found no earthly reason why that happened, I tried reducing the amount of indexing in the for() loop. Everything works fine now.

STL vector subscripts are pretty straightforward -- they inline to simple C-style array subscripts. No reentrancy issues to speak of.
When you "reduced the indexing", did you assign to a signed or unsigned temporary variable for the intermediate index?
No. What I did, was get the ref to the indexed structure, and used that afterward. So for each of the structures involved, there is a single someStruct * = &(a->someVector[i]); then for the rest of the loop it is merely someStruct->field;
Probably lightens up on the cpu a bit, too.
