GDB is unable to find the start of the function at 0x433a2f74 and thus can't determine the size of that function's stack frame. This means that GDB may be unable to access that stack frame, or the frames below it. This problem is most likely caused by an invalid program counter or stack pointer. However, if you think GDB should simply search farther back from 0x433a2f74 for code which looks like the beginning of a function, you can increase the range of the search using the `set heuristic-fence-post' command. Program received signal SIGSEGV, Segmentation fault. 0x433a2f74 in ?? () (gdb)
