gcc 4.4.1 generates incorrect code for the following type of expression:
void *P;
for (something) {
...
*((*(int **)&P)++) = Value;
...
};
P remains unchanged throughout the loop.
This code worked correctly in earlier versions of gcc, last checked on gcc
4.3.2.
the following flags were used:
-std=gnu99 -fdata-sections -ffunction-sections -pipe -O2 -fomit-frame-pointer
-w -D_GNU_SOURCE -fexpensive-optimizations
