While fixing bug 676, I ran into a very strange memory corruption situation:
Like in the tie-engraver.cc, I used vectors in tie-performer.cc to store the
moment together with the Audio_element_info.
Now, this always led to memory corruption as soon as I called push_back.
Before the push_back call, the size() of the vector was 0, after the
push_back, the size() would be reported as 3303820998 (instead of 1)?!?!?
Using a deque instead of a vector works just fine.
In particular, the commit 4ba35b32beca41dce222a95a5e0ed0c959e867dd using
vector will always crash with the following file:
\version "2.11.58"
\score {
{ c ~ d c d }
\layout { }
\midi { }
}
On the other hand, changing vector to deque in commit
b238aa006f301fe8c194a1329af75f9db9b3024b will work just fine.
The size() issue I mentioned above can be seen by commenting out the two
message(..) calls in the latter commit and switching back from deques to
vectors.
Any idea what might be the problem here?
Cheers,
Reinhold
