SIGSEGV, segmentation fault when using fstream

[charan manju]

Hi,
In my application, i used fstream, It is working fine in windows, causing segmentation fault in Linux. Please, give me your suggestions.

The following is the debugger output, gdb o/p for bt

You'll need to post some code that reproduces the problem.

Looks like you may have some memory corruption. Try running it through Valgrind. I recommend dumping its output to a file so you can read it once the program crashes. Oh, can compile with no optimizations and with debug information.
