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.
Cheers,
Birger
