You're passing a value to sqrt which has not been initialized i. I guess there's a problem with those linking libraries of gtkmm? Thanks for pointing it out. Updates to the mapping are not visible to other processes mapping the same file, and are not carried through to the underlying file. Have you tried searching the net for that error? For a file that is not a multiple of the page size, the remaining memory is zeroed when mapped, and writes to that region are not written out to the file. I just pulled the latest version and it's running now.
Please enter compnay from list. But that issue is not specific to purchaseShares. By default, any process can be killed at any moment when the system runs out of memory. Quote: it seems likely that something is writing to memory it shouldn't be. The file may not actually be updated until 2 or munmap is called. Otherwise, or if free ptr has already been called before, undefined behavior occurs.
I really do not known why? On the other hand, closing the file descriptor does not unmap the region. Assigning string literals does not have the effect of copying their content as you might have thought. This will leave some trash elements remaining in the heap so some further operations which? I'm probably the biggest single user, but I'm happy to cede that crown. But that also doesn't narrow the possibilities much. Here is my makefile Here is my mainfile And here is an additional file Any help is appreciated. Later accesses to the mapping will not be blocked by page faults. Hi guys, I have this error, too.
Sorry, I obviously have lost sight of what people can do when starting out. Please tell me why and when this error should happen? The others are all saying that you're using memory that has not be initialized with a known value. This won't solve your problem, but will show which assignment to the vector causes error. It will also be a lot faster - you save a whole pointer indirection. I really do not known why? Sorry, I have did the google but the explicit reason is inavaiable.
I don't think there is any doubt of that. When you call free on the pointer later on, the program crashes because you pass a pointer to free that has not been obtained through malloc. The bottom line is that the pointer passed to free must be the same as returned by malloc , realloc and their friends. Can you use a debugger and tell us exactly which line is generating the error? This is not an analytical answer to the question but a piece of advice with respect to solving or better circumventing the problem. It's more productive to figure out the issue manually and learn how to avoid it in the future. Elements in the vector are deconstructed as well.
And I need your help. You should use here strcpy as also suggested by others. Instead a lot of different beginning programmers have made many different mistakes, each of which was detected by glibc during release of some resource. This happened with a git checkout from last friday, pulled from git today, the same. Can you shortly describe your environment? The most common and simplest bug with this symptom is writing past the end of an array allocated with malloc or with new in C++. Showing more code might help like showing loadData and getCompanyName , but what would help more is if you copied your code into another project, and then whittled down the code to create a minimal example that we can compile to reproduce the problem. And it is very likely that you actually can avoid it.
And I need your help. If so, the compiler will have generated one for you. Can you pull latest and see if you can still reproduce the problem? I just pulled the latest version and it's running now. I tried compiling with -O0 -ggdb -g3 -fstack-protector-all but with no success. What's happening is that you are corrupting the heap somewhere else in your program and this is where it happens to manifest.
Memory mapped by mmap is preserved across 2 , with the same attributes. I have problems with running my unit tests 1. Problem appears when I use MultipliedByMatrix method. It can't properly delete the matrix that was created in this method. The problem is that when i run the application, i get this error:. You should use here strcpy as also suggested by others. I've been using philesight for a while and, while migrating the internal web server, I discovered duc.
