From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: I am using the LINUX 9 and gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5) I am some C codes and linked these code to form a shared object as libqpt.so. Now i use this SO file and run the main file which has large arrays declared for the worspace and others etc. when i run the code i get segmentation fault due to variables declared are cossing the data segment and the stack size. Hence i modified my code and used the malloc for those arrays used. I got partial output and segmentation fault occurs again. Please anybody can hep me out to increase the stack size as we can do in the Visual Studio. Note i have no IDE i am running the code in the terminal. Please do giv me any possible solutions for the problem. My thanks in early. Mail the solution to me at: maheshsk17@rediffmail.com Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.there are no special setups i just run the code using the command: gcc -rdynamic -L./ -lqpt -lm -o qpmain qpmain.c output i get is: Segmentation Fault. Actual Results: i obtained the partial output in the output file and later same result segmentation fault is faced. Expected Results: an output file has to be generated.
You can tweak the limits with ulimit(1) or setrlimit(2). Sometimes if the allocations are really huge statically linking helps as well, or going for a 64-bit CPU. But, bugzilla is certainly not a help forum, you should try mailing lists.
