Assertion failing when I write to ofstream& in function

[biot023]

Hi.
I have a function that looks exactly like this:

void Tga_string::write_to_file(ofstream& file)
{
if(file.is_open()){
for(u_int indx(0);indx<Fcommands.size();indx++)
file<<Fcommands[indx]->command_string().c_str()<<endl;
file<<&quot;//END\n\n&quot;;
}
else
throw Efile_nopen(&quot;ga string file&quot;
}

The trouble is, whenever I call it, I get a wierd message saying:
Assertion failed: !&quot;bogus context in _ExceptionHandler()&quot;, file xx.cpp, line 3071

Then I get an abnormal program termination to OK, & then I am bounced to the CPU box, which is WAY out of my league.
I can create the file & write to it in the main body of my code, so why won't it work here?
The line it falls over on is:
file<<Fcommands[indx]->command_string().c_str()<<endl;

All other functions checked out here are fine - the command_string() function simply returns an STL string & checks out OK.
Can anybody offer any help?
I'm deeply baffled!

Common sense is what tells you the world is flat.

I've altered the function so that it now reads:

void Tga_string::write_to_file(ofstream& file)
{
if(file.is_open()){
string line;
for(u_int indx(0);indx<Fcommands.size();indx++){
line=Fcommands[indx]->command_string();
file<<line.c_str();
file<<endl;
}//next indx
file<<&quot;//END\n\n&quot;;
}
else
throw Efile_nopen(&quot;ga string file&quot;
}

Now the file just gets filled with '\n' characters for the number of iterations of indx.
I am SERIOUSLY confused!
I hate to say it, but this is looking like a BCB6 bug somewhere.
Anyone any ideas what might be going wrong?
Or how to fix it?
Cheers,
