[SCIP] Program terminated with error at SCIPfree(&scip)

[Gerald Gamrath]

Dear Xiangyong,

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.

Best,
Gerald
