Hi..
i'm getting core dump after the "system" command of unix although the command is successful.
i'm pasting the dump below..

at iclsn_handler.c:1050
1050 sprintf(commandLine, "rm -f %s%s%s", inputFilePath, baseFileName,input_ext);
(gdb) n
1051 rc = system(commandLine);
(gdb) p commandLine
$1 = "rm -f /cygdrive/c/source/bins/test/ACTV_IC_000000_20040809_082000.FIN\000", ' ' <repeats 930 times>
