Bug#2087: ppmforge seg faults
Package: pbmplus
Version: 10dec91 Rev 2
ppmforge -stars produces an image which appears to be truncated, then
stops with a Segmentation fault error.
Example:
% ppmforge -stars 0 > junk
ppmforge: planet: -seed 1357751156 -dimension 2.40 -power 1.20 -mesh 256
ppmforge: -inclination 18 -hour 12 -ice 0.40 -glaciers 0.75
ppmforge: -stars 0 -saturation 125.
Segmentation fault
This error appears to be independent of the numeric option given to
stars. That is, the program also segfaults with "-stars 100".
If one then attempts to show the output image with 'xv', the result is
an error message "junk: file appears to be truncated". Despite this,
xv succeeds in showing that part of the image which is not truncated (which is
98% of it).
Two other options fail in the same way:
ppmforge -clouds
ppmforge -planet
The portion of the image which is being truncated can be illustrated
fairly dramatically using:
ppmforge -clouds | xv -root -quit -
On the other hand, this succeeds:
ppmforge -stars
Interestingly, this is the only one of the options which produces
only black and white output.
