Hi, when debuggin my own program I found the following problem in TApplication (pro-version of root): ==27774== Mismatched free() / delete / delete [] ==27774== at 0x40047606: __builtin_delete (vg_clientfuncs.c:186) ==27774== by 0x408CE03A: TApplication::~TApplication(void) (in /afs/desy.de/products/ROOT/3.02_07-rfdc/gcc-2.95.3/root/lib/libCore.so) ==27774== by 0x804B537: main (i386_linux24/../clusters_ods.C:147) ==27774== by 0x41622C5F: __libc_start_main (in /lib/libc.so.6) ==27774== Address 0x46B8105C is 0 bytes inside a block of size 13 alloc'd ==27774== at 0x400474A8: __builtin_vec_new (vg_clientfuncs.c:152) ==27774== by 0x4090B8B0: StrDup(char const *) (in /afs/desy.de/products/ROOT/3.02_07-rfdc/gcc-2.95.3/root/lib/libCore.so) ==27774== by 0x408CDD0F: TApplication::TApplication(char const *, int *, char **, void *, int) (in /afs/desy.de/products/ROOT/3.02_07-rfdc/gcc-2.95.3/root/lib/libCore.so) ==27774== by 0x804AB2A: main (/products/gcc-2.95/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/../../../../include/g++-3/iostream.h:106) This is due to the use of ./base/inc/TString.h:extern char *StrDup(const char *str); //duplicate // str, free with delete [] in the lines for (int i = 0; i < fArgc; i++) fArgv[i] = StrDup(argv[i]); of the constructor of TApplication with a corresponding for (int i = 0; i < fArgc; i++) SafeDelete(fArgv[i]); in the Destructor which is actually a ./base/inc/RConfig.h:#define SafeDelete(p) { if (p) { delete p; p = 0; } } So instead of SafeDelete something like if(fArgv[i]) delete [] fArgv[i]; should be used.
