Dear Xiangyong,<br>
<br>
in order to get best results for debugging your code with valgrind,
please compile both SCIP and your application with NOBLKBUFMEM=true.
This will disable the block and buffer memory of SCIP which hinders
valgrind to detect all invalid reads and writes.<br>
<br>
Best,<br>
Gerald<br>
