A sudden error using TMinuit

Dear Rooter,

I've got an error, during the execution of my program. I use TMinuit object within TF2 constructor and TGraph2DErrors class ( myfunc->Fit("whatever","R"); )

The error is:

"dlopen error: libstdc++-libc6.1-2.so.3: cannot open shared object file: No such file or directory
Load Error: Failed to load Dynamic link library /home/lhc1/cern/root/lib/libMinuit.so

• Break *** segmentation violation Generating stack trace... 0xa7119a32 in TGraph2D::Fit(TF2*, char const*, char const*) + 0x81e from /usr/lib/root/libHist.so.5.13 0xa7117836 in TGraph2D::Fit(char const*, char const*, char const*) + 0xd4 from /usr/lib/root/libHist.so.5.13 0x08052295 in main + 0x4a3 from dis 0xa654fea8 in __libc_start_main + 0xc8 from /lib/tls/libc.so.6 0x0804b9f1 in TApplicationImp::ShowMembers(TMemberInspector&, char*) + 0x4d from dis Abort"

This error occured suddenly during the last run of the code, I changed nothing in my program and untill the last run, everything was O.K....

How can I resolve the problem?

Thanks!
