Hi Andrew:
I get the following valgrind result with C++ example 33:
==9193== Mismatched free() / delete / delete []
==9193== at 0x4C23E0F: operator delete(void*)
(vg_replace_malloc.c:387)
==9193== by 0x406A70: x33::x33(int, char const**) (x33.cc:823)
==9193== by 0x406AF4: main (x33.cc:830)
==9193== Address 0x6ef3b90 is 0 bytes inside a block of size 200
alloc'd
==9193== at 0x4C24A72: operator new[](unsigned long)
(vg_replace_malloc.c:305)
==9193== by 0x403F26: x33::x33(int, char const**) (x33.cc:278)
==9193== by 0x406AF4: main (x33.cc:830)
>From these messages it appears something is wrong with the
allocation/deallocation of the text character string used for
pllegend. The relevant code is
char *text[MAX_NLEGEND];
for ( k = 0; k < MAX_NLEGEND; k++ )
text[k] = new char[200];
for ( k = 0; k < MAX_NLEGEND; k++ )
delete text[k];
That seems OK to me, but I don't have much C++ experience. Is there
something obviously wrong with the above code? If it is okay, but
valgrind is being over-sensitive, is there a way we can quieten
valgrind?
