Hi, I've recently encountered this error on my system:

Error accessing memory address 0x0: Input/output error. (gdb) I've no clue on where this "breakpoint -1" comes from. "myprogarm" is a C++ programs linked with C++ template-based libaries, including STL & Boost. Any hint on what to check for this type of problem is appreciated. --- Jeffrey
