Summary0001775: sfdp crashes when -Goverlap=scale or scalexy is used
Description
When sfdp is used with -Goverlap=scale or -Goverlap=scalexy, segfaults occur.
Additional Information

[erg]
Given that your input graph has 87000 nodes and the nodes are not drawn as points, using overlap=scale is going to
cause an enormous blow-up and the bug probably involves numerical overflow or
something related. For large graphs, the only practicable
value for overlap is prism.

[erg] The problem was that memory was being exhausted. The scale
code was using realloc rather than RALLOC. That has been changed,
so now sfdp will exit instead of crash.
TagsNo tags attached.
