Problem with TFileMerger

Dear ROOTers,

I wrote a macro that tries to merges files using TFileMerger. When I run the macro, if I use less than 5 files, all works fine, but if I use more files, when I call the Merge method, I receive the message (obtained with gdb root.exe , catch throw and after run root .exception and then execute the macro) you can find below.

Could someone help me?

Thanks in advance,

Melinda
