search for: uninitialised

Hi, I'm using valgrind to check over some C/C++ code for an R library. I'm getting the report (see below), but can't track down the uninitialised value(s). I tried using --track-origins=yes in valgrind which gives: ==28258== Uninitialised value was created by a stack allocation ==28258== at 0xEE33D98: ??? (in /usr/lib64/R/lib/libRlapack.so) I presume the problem is an uninitialised value being used in my code, rather than in libRl...

...is a GPL'd tool to help you find memory-management problems in your programs. When a program is run under Valgrind's supervision, all reads and writes of memory are checked, and calls to malloc/new/free/delete are intercepted. As a result, Valgrind can detect problems such as: * Use of uninitialised memory * Reading/writing memory after it has been free'd * Reading/writing off the end of malloc'd blocks * Reading/writing inappropriate areas on the stack * Memory leaks -- where pointers to malloc'd blocks are lost forever * Passing of uninitialised and/or unaddre...
