Lots of Errors

ROOT
1

[code]void
infinite_loop_of_segmentation_violations()
{
string foo;

    sprintf(foo.c_str(), "foo");

}
[/code]

I know I have to use

[code]void
foo()
{
Char_t foo[0];

    sprintf(foo, "foo");

}
[/code]

but I was thinking that countless error messages are bug?

Hello Dimitar,

I can not reproduce this problem. It is probably due to diffierence of environment. So far, I’ve tried with MacOS-X, Windows-XP VC++7.0
and Windows-XP Cygwin5.1.

What kind of errors are you seeing?

and this is repeating forever:)

As you see I don’t have local instalation of ROOT and I’m using:
setenv ROOTSYS /afs/cern.ch/sw/root/v4.01.02/rh73_gcc296/root
setenv PATH ${ROOTSYS}/bin:${PATH}
setenv LD_LIBRARY_PATH ${ROOTSYS}/lib:${LD_LIBRARY_PATH}

Hello,

It looks like the errors are comming from ROOT. I guess what Rene
tries to say is that if this is a ROOT error, you should post it in
ROOT support forum. Probably, it is a bit difficult for an innocent
user to tell whether the errors come from Cint or ROOT. Anyway, please
consult Rene, Fons or Philippe for solving this problem.

Thank you
