--- Begin Message ---Package: ftjam Version: 2.5.2-1 jam0 segfaults (at least on powerpc) when I compile it with a snapshot of GCC 4.2. I'm not entirely sure whether this is a compiler bug or one in your package, but from other cases like these it is likely that your package is doing something wrong and that newer optimizations exhibit the problem. Maybe you or your upstream can investigate. If everything fails, I can try to find someone who knows C/GCC well. I've done some preliminary investigation which shows where the error is. When you compile jam0 with gcc 4.2 (from the gcc-snapshot) package, you'll get a segfault. When you drop the optimization for rule.c to -O1, it works. So the problem seems to be there. FWIW, when I ran gdb on different binaries, I got two different tracebacks. This seems to be related to #367825 where bjam segfaults. > Automatic build of ftjam_2.5.2-1 on test.track.rz.uni-augsburg.de by > sbuild/powerpc 0.44 ... > make[1]: Entering directory `/build/tbm/ftjam-2.5.2' > gcc -o jam0 -g -O2 builtins.c command.c compile.c execnt.c execunix.c > execvms.c expand.c filent.c fileos2.c fileunix.c filevms.c glob.c hash.c > hdrmacro.c headers.c jam.c jambase.c jamgram.c lists.c make.c make1.c > newstr.c option.c parse.c pathunix.c pathvms.c regexp.c rules.c scan.c > search.c timestamp.c variable.c > execunix.c: In function 'execcmd': > execunix.c:235: warning: incompatible implicit declaration of built-in > function '_exit' > chmod a+w jambase.c > ./jam0 > make[1]: *** [all] Segmentation fault > make[1]: Leaving directory `/build/tbm/ftjam-2.5.2' > make: *** [build-stamp] Error 2 [EMAIL PROTECTED]:/build/tbm/ftjam-2.5.2$ gcc -o jam0 -g -O2 builtins.c command.c compile.c execnt.c execunix.c execvms.c expand.c filent.c fileos2.c fileunix.c filevms.c glob.c hash.c hdrmacro.c headers.c jam.c jambase.c jamgram.c lists.c make.c make1.c newstr.c option.c parse.c pathunix.c pathvms.c regexp.c rules.c scan.c search.c timestamp.c variable.c execunix.c: In function 'execcmd': execunix.c:235: warning: incompatible implicit declaration of built-in function '_exit' [EMAIL PROTECTED]:/build/tbm/ftjam-2.5.2$ ./jam0 Segmentation fault [EMAIL PROTECTED]:/build/tbm/ftjam-2.5.2$ gcc -c -O1 -o rules.o rules.c [EMAIL PROTECTED]:/build/tbm/ftjam-2.5.2$ gcc -o jam0 -g -O2 builtins.c command.c compile.c execnt.c execunix.c execvms.c expand.c filent.c fileos2.c fileunix.c filevms.c glob.c hash.c hdrmacro.c headers.c jam.c jambase.c jamgram.c lists.c make.c make1.c newstr.c option.c parse.c pathunix.c pathvms.c regexp.c scan.c search.c timestamp.c variable.c rules.o execunix.c: In function 'execcmd': execunix.c:235: warning: incompatible implicit declaration of built-in function '_exit' [EMAIL PROTECTED]:/build/tbm/ftjam-2.5.2$ ./jam0 ...found 143 target(s)... ...using 1 temp target(s)...
