Description Robin Humble 2006-04-11 16:20:38 UTC

Description of problem:
pnmtopng dumps core and fails to work

Version-Release number of selected component (if applicable):
netpbm-10.33-0.FC4

How reproducible:
100%

Steps to Reproduce:
1. pngtopnm /usr/share/icons/Bluecurve/48x48/apps/redhat-system_settings.png |
pnmtopng > red.png

Actual results:
pnmtopng: nstring.c:940: vasprintfN: Assertion `str_l2 == str_l' failed.
Abort (core dumped)


Expected results:
producing an image

Additional info:
it works on some images. eg.
  ppmmake red 10 10 > red.ppm
  pnmtopng < red.ppm > red.png
but doing the same thing in one line does not work (hits the same assert() as
above):
  ppmmake red 10 10 | pnmtopng > red.png

as another example, this works
  pngtopnm /usr/share/icons/Bluecurve/48x48/apps/redhat-system_settings.png |
pnmquant 256 > red.ppm
  pnmtopng < red.ppm > red.png
but without the pnmquant it does not work (same assert again):
  pngtopnm /usr/share/icons/Bluecurve/48x48/apps/redhat-system_settings.png >
red.ppm
  pnmtopng < red.ppm > red.png

Ok, pnmtopng will fail with the error even if it's called with no arguments on
x86_64. The error doesn't occur on 32bit arches. The culprit is the code in
nstring.h, which is now fixed in rawhide.

netpbm-10.33-1.fc5 has been pushed for fc5, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
