![]() ![]() Therefore, to make programs compiled with sanitizers work on Aisa, you need to reset the limit: ulimit -v unlimited. Please note that virtual memory need not be actually used, so it is possible to allocate much more of it than there is physical memory on the system (this is called memory overcommit). Sanitizers use this memory to associate shadow data to you allocations using arithmetics on addresses. The reason for this is that sanitizers allocate large blocks of virtual memory (in the order of tens of terabytes). Note: On Aisa, there is a virtual memory limit of 256GB – while this seems like something that cannot be a problem for our small programs, it actually is a problem for programs which use sanitizers. Note however, that memory sanitizer can have problems tracking if memory is defined when it was set inside the standard library, for this reason, it is better to use valgrind for checking if memory values are properly defined. ![]() Useful are mainly AddressSanitizer (invalid memory access
