Red Hat Bugzilla – Bug 199700
Output catalog has pixel positions for all sources set to 0,0
Last modified: 2007-11-30 17:11:38 EST
Description of problem:
The program runs perfectly but the output catalog has the pixel position of all
detected sources fixed to 0,0 and the RA-DEC coordinates are all the same
(corresponding to pixel 0,0).
Version-Release number of selected component (if applicable): 2.5.0-1.fc5
How reproducible: Perfectly
Steps to Reproduce:
1.Download image and sextractor input file from
2.Run sextractor outputting the following parameters:
3.Check output catalog.
Actual results: All pixel positions set to 0,0
Expected results: Different pixel positions and RA-DEC's for each source.
Additional info: Version directly downloaded from
The problem seems to come from the different compilation options of the home
made sextractor rpm and the fedora rpm.
The fedora rpm is compiled with, between other options, -O2
The rpm made by the sextractor people is compiled with -O1
As I have tested, the inclusion of -O2 of the fedora rpm produces the errors. I
will tell upstream and I will produce a new rpm optimized with -O1 insted of -O2
It seems that changing the flags breaks the debugging info of the package. I
have reverted the flag from -O1 to -O2 again.
Additionally, the rpm seems to work in FC4. There exists a problem with the
source and gcc 4.1
