/usr/lib64/libgslcblas.so.0.0.0Abort Version-Release number of selected component (if applicable): 3.7.0-8.fc12.x86_64 How reproducible: Always Steps to Reproduce: 1.Read an image with a long header and RA---TAN-SIP, DEC--TAN-SIP WCS system. 2.Try to use wcsinit. 3. Actual results: Program Aborted before wcsinit finishes. Expected results: wcsinit should run and allow to use other wcstools functions. Additional info: The problem occurs when calling wcsinit. Problem goes away if header of FITS file is edited and CTYPE1 and CTYPE2 keyword values are changed from RA---TAN-SIP and DEC--TAN-SIP to RA---TAN and DEC--TAN. Problem is not existent when working with the same original FITS image in FC11, wcstools version 3.7.0-7.fc11.x86_64. Problem is not existent when using own compilation of wcstools version 3.8.1.
Pablo, thanks for the bug report. Could you put somewhere a sample FITS that makes the application crash?
Here it is: http://guaix.fis.ucm.es/~pgperez/temp/thdfn_all_ch1_m.fits And the code I was running: struct WorldCoor *rwcs; string rname="thdfn_all_ch1_m.fits"; char *header; int lhead,nbhead; rfile=new char [rname.length()+1]; strcpy(rfile,rname.c_str()); header=fitsrhead(rfile,&lhead,&nbhead); rwcs=wcsinit(header); //Abort is produced in the previous line!!!! wcs2pix(rwcs,esa1,esa2,&wx,&wy,&off); ...
I'm testing wcstools 3.8.1 The size of field c1type in struct WorldCoor is 9, but the value copied into it is 'RA---TAN-SIP', whose length is 12. There are other fields with numeric values, such as radecsys[32] or ctype[9][9]. I don't feel I can fix the bug without the danger of creating new problems I will report the bug upstream, If the maintainer creates a fix, I can patch the fedora package
wcstools-3.8.1-1.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/wcstools-3.8.1-1.fc12
wcstools-3.8.1-1.fc11.1 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/wcstools-3.8.1-1.fc11.1
wcstools-3.8.1-1.fc12 seems to have solved the issue. And it has also solved a related problem in ds9, which aborted when loading the same type of image. Thanks.
