Description of problem: pnmrotate: free(): invalid pointer 0x8a27be0! Version-Release number of selected component (if applicable): netpbm-progs-10.19-7 How reproducible: #!/bin/bash echo P2\ 1 1\ 255\ 0\ > tmp.pgm pnmscale 4 tmp.pgm | pnmrotate 10 > tmp1.pgm Steps to Reproduce: see above Actual results: pnmrotate: outrows=5 bgxel red=0 pnmrotate: top left pixel red = 0 pnmrotate: outrows=5 bgxel red=0 pnmrotate: top left pixel red = 0 pnmrotate: outrows=5 bgxel red=0 pnmrotate: top left pixel red = 0 pnmrotate: outrows=5 bgxel red=0 pnmrotate: top left pixel red = 0 pnmrotate: outrows=5 bgxel red=0 pnmrotate: top left pixel red = 0 free(): invalid pointer 0x8330be0! Expected results: cat tmp1.pgm P5 6 5 255 Additional info: I'm - submitting this on behalf of a professor who often uses netpbm package. I'm -in certainly not experienced user of netpbm, but I think- I fixed it with the the small modification, for now. Likewise, you'll find the program fixed in 10.22 . Plugging netpbm-10.22 as source for -rebuilding the SRPM via netpbm.spec fails -because of several patches included in netpbm-10.19 etc. The user considers the netpbm-progs to be broken -likely because he has shell scripts -that fail because of this problem. : root@regulus editor; diff -Naur pnmrotate.c pnmrotate.c.orig --- pnmrotate.c 2004-06-15 09:48:35.403519181 -0500 +++ pnmrotate.c.orig 2004-06-15 09:47:57.226359735 -0500 @@ -342,8 +342,8 @@ for (outrow = 0; outrow < outrows; ++outrow) outxels[outrow][col] = bgxel; -/* pm_message("outrows=%d bgxel red=%d", outrows, PPM_GETR(bgxel)); -pm_message("top left pixel red = %d", PPM_GETR(outxels[0][0])); */ +pm_message("outrows=%d bgxel red=%d", outrows, PPM_GETR(bgxel)); +pm_message("top left pixel red = %d", PPM_GETR(outxels[0][0])); prevxel = bgxel; for (inrow = 0; inrow < inrows; ++inrow) { int const outrow = inrow + intnew0; @@ -633,7 +633,7 @@ } pnm_freerow( newxelrow ); - pnm_freearray( temp2xels, newrows ); + pnm_freearray( temp2xels, rows ); pm_close( stdout ); exit( 0 );
