runtime error in ExRootLHEFConvert: pointer being freed was not allocated

Asked by Roberto Franceschini

Hello I am on Mac OS X 10.9.2 and I got to compite ExRootAnalysis 1.0.12.
Unfortunately all the executables from ExRootAnalysis, for instance ExRootLHEFConverter, give errors like the following:

./ExRootLHEFConverter
ExRootLHEFConverter(21781,0x7fff79232310) malloc: *** error for object 0x7fff79112330: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

On the other hand the library in lib/libExRootAnalysis.so seems to work fine when I compile it in my bigger code that makes use of it to read ROOT files from, say, the Madgraph cluster.

I am rather puzzled by this error at run-time, any suggestion?

Thanks for helping,
Roberto

Does it help if I add that this error appears both with gcc 4.8.1 and 4.9? Does it make sense to try other compilers? can the compiler be the problem?

I have tried as well ExRootAnalysis 1.0.9 but still the error is:

ExRootLHEFConverter(39902,0x7fff7a355310) malloc: *** error for object 0x7fff7b525330: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

I tried also the lldb debugger of Mac OS X 10.9 and the output is

ExRootAnalysis>lldb ExRootLHEFConverter

(lldb) run
