Bug ID: 63643
Summary: pointer to const variable doesn't allow to change its
value (on Mac OS)

Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c

A program which tests changing a const value with a pointer.
For example, when a variable i is declared as const int, and p is declared as
int *, it is impossible to change the value of i by *p, whereas ANSI norm
allows it.
More over, it seems to be two differents value at the same address. Here is the
result of a test:
0x7fff5720dbf8 : 0
0x7fff5720dbf8 : 12
You'll find the program in attachment.
