Hi, I'm speech recognition researcher not so fond of newer Linux systems. I have some old ansi C code that I used to run under Debian 2.0. Now I transferred code to Suse 9.0, compile it without any errors (some warnings) but get segmentation faults in runtime. One particular error is (I get this when run in ddd): Program received signal SIGSEGV, Segmentation fault. 0x400b90af in fflush() from /lib/libc.so.6 ---------------- My C knowledge is rusty (I checked up this code long time ago) so I'd kindly ask for some quick guidance, how to deal with such segfaults. If I remember right there were some tools that could help in debugging memory accesses (efence or something like that) - I guess tools are now much more advanced - but I don't know which one to use... Also any advice on this particular error would be appreciated. Thanks in advance, regards, Robert.
