When emerging gnuplot, the build fails with a segmentation fault while attempting to build the documentation. It fails with both the stable 4.2.6 and the unstable 4.4.0. Reproducible: Always Steps to Reproduce: 1.emerge -1v gnuplot with doc use flag set 2. 3. Actual Results: Fail. When the doc use flag is turned off, gnuplot builds just fine. Rebuild texlive-latex doesn't help any; I still get the same error.

Everything looks fine here, it seems that this is more a problem with texlive than gnuplot. I cannot imagine any Latex source that will make texlive segfault. Can you try pdflatex on some other .tex files ?

When I emerge gnuplot on another x86 box I have, the gnuplot tutorial builds fine with the doc USE flag. It's definitely related to pdflatex, because if I go into the /var/tmp/portage build directory and run pdflatex directly on the tutorial.tex file I get the same segfault. gdb backtrace shows the segfault is in strlen in glib. strace seems to point to a problem with the font files perhaps:? open("/var/cache/fontconfig/87f5e051180a7a75f16eb6fe7dbd3749-x86.cache-2", O_RDONLY) = 9 fstat64(9, {st_mode=S_IFREG|0644, st_size=33624, ...}) = 0 mmap2(NULL, 33624, PROT_READ, MAP_SHARED, 9, 0) = 0xb4898000 close(9) = 0 stat64("/usr/share/fonts/encodings/large", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 open("/var/cache/fontconfig/5ca8086aeacc9c68e81a71e7ef846b3b-x86.cache-2", O_RDONLY) = 9 fstat64(9, {st_mode=S_IFREG|0644, st_size=88, ...}) = 0 read(9, "\4\374\2\374\2\0\0\0X\0\0\0 \0\0\0H\0\0\0\0\0\0\0H\0\0\0A\331#K"..., 88) = 88 close(9) = 0 brk(0x8613000) = 0x8613000 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Segmentation fault In any case, this is starting to look more like an issue on this one system than a bug in gnuplot per se. I'm going to see if I can get more help on the forums, and I'll close this bug as INVALID for gnuplot for now. Thanks!
