dot -Tsvg

on the file I attached, we get:

Segmentation fault, core dump

same error does not occur when we run under RedHat linux.
Input:

see attached file (long and ugly, sorry).

[erg] Core dumps on sgi. The problem is clearly related to the label size. To get a core dump, it is sufficient to reduce the graph to the single edge 75 -> 76.
Fix:
Avoided fixed character array for potentially big output such as labels and comments.
