1) It's more likely to work if the replacement string is the same
length as the replaced string, such as:
s/_ZNSt6vector/_ZNSt6vectoX/
not s/_ZNSt6vector/_ZNSt6vectorX/
That's an important part of the trick, if you're going to be
using sed to hack binary files.
2) A prefix that short is brutal indeed. In fglrx_dri there are
57 symbols that begin with _ZNSt6vector ... I thought there was
only one function that had been identified as a troublemaker.
3) I would try
strings /usr/lib/dri/fglrx_dri.so | grep vector.*reserve
expecting to see something like
_ZNSt6vectorI13ShUniformInfoSaIS0_EE7reserveEj
_ZNSt6vectorIi14pool_allocatorIiEE7reserveEj
* _ZNSt6vectorIiSaIiEE7reserveEj
vector::reserve
of which the one that most resembles the starred version is the
one that needs to be hacked.
Unless fglrx_dri has more than one bug :-( .......
