Make sure you don't use '-s' flag when linking the executable (at least during development). That flag causes ld to remove symbol table information from the executable. > and also does this message make sure that, signal is caught during a > memcpy operation? I would think so. memcpy() is a likely candidate for causing SIGSEGV - one of the pointers passed to it may be invalid. Ravi.
