attempt to use poisoned "malloc"?

[Steven Z]

Hi, there:

I used to work on changing gcc-3.3 with compiler gcc-2.97. My system
crashed and I reinstalled RedHat FC2. The default compiler on FC2 is
gcc-3.3.3. Then the used-to-work codes generates error like:
    attempt to use poisoned "malloc"

I tried to change malloc to calloc. That makes no difference other
than generating error message like:
    attempt to use poisoned "calloc"

Does anyone have any idea on why this error is generated? What is
possible solution? Does this have anything to do with different
versions of gcc?

Any reply will be appreciated.

Good day,
Steven
