Description of problem: The following test scripts (all.tcl) failed. Some of them are core dumped or aborted. 1. install tkimg-1.30.10.20080505svn and tkimg-devel-1.30.10.20080505svn from yum repository 1. rpmbuild tkimg-1.3-0.10.20080505svn.fc9.src.rpm (rpm -i and rpmbuild -bp). 2. move to BUILD/tkimg-20080505 3. move to each tests directory 4. run "wish all.tcl" ico/tests/all.tcl ==== ico-1.1 FAILED pixmap/tests/all.tcl ==== bmp-1.1 FAILED ==== bmp-2.0 Binary I/O with BMP images FAILED (after addinf folder.bmp from tests, all succeeded) png/tests/all.tcl segmentation fault sgi/tests/all.tcl ==== sgi-1.1 FAILED ==== sgi-1.2 FAILED ==== sgi-1.3 FAILED *** glibc detected *** wish: malloc(): memory corruption: 0x00000000009fff50 ***
I am getting segfaults from the same tkimg version for fc8, which seems likely to be caused buy the same problem. It can be reproduced with the following tclsh input: package require img::png image create photo ::img::spot_red_plus3x3 -data "iVBORw0KGgoAAAANSUhEUgAAAAMAAAADCAYAAABWKLW/AAAABmJLR0QA/wD/AP+gvaeTAAAACXBIWXMAAAsTAAALEwEAmpwYAAAAB3RJTUUH1gYdDTo2x0v3wwAAAB10RVh0Q29tbWVudABDcmVhdGVkIHdpdGggVGhlIEdJTVDvZCVuAAAAG0lEQVQI12NgYGBg+M/A8J+BgYGBEcaAA5gAAHzEBfwZ/LSpAAAAAElFTkSuQmCC" It doesn't crash every time. When it does, it is crashing during a call to png_read_info() in libpng12.so. I tried switching to older versions of tkimg, and an older version of libpng, but still get the segfault. I can send more info, but hopefully the above example can reproduce the crash.
Ok, I can reproduce the crash in f8 and f9, with tkimg-1.3 The past week I submitted a new tkimg-1.4 for devel and f10 and it seems to crash too. :( The rpm package is patched to use the system libraries instead of the libraries in the package. I will try recompile tkimg without the patches and see what happens
After my comment above, I tested the SRPM patched sources. It seems that the patches are the problem. However, I think using system libs is the right thing to do. Tkimg really should have a built-in option whether to include it's own libraries. It seems that Tkimg is not maintained much; it still uses K&R syntax. My suggestion is to build new RPMs without the system-lib patch, and try to work on improving the Tkimg sources for a future release.
The png driver uses two callbacks that aren't exported anymore by the dynamic png library, png_read_destroy and png_write_destroy. To allow the compilation I have removed them in pngtclDecls.h and pngtclStubInit.c I don't know, but this can be the reason of the crash. I will bug this upstream
Several other image formats have problems as well, even though PNG is the only one to segfault. I still think it is worth releasing a version without the system-lib patch until this gets worked out.
