[Valgrind-users] Invalid write of size 4 and ...

[Xiang Y. <xy...@pr...>]

Hello,

redhat linux ads/glibc 2.2.4/gcc2.96/pthread
I'm using Oracle call interface apis in my app which is hard for me to =
trace. I have two questions:
1. there is a malloc(24) (// any constant) crashs the app outside =
valgrind, in valgrind however, it's just fine=20
:( . any more clues on this?  =20
2. I have two errors in following oci call:

Can I have more insight on "Address 0x41B6BA44 is 8 bytes after a block =
