[SCIP] Memory Allocation

[Wang, Tony Congqian]

Hello,


I have found a bug in branch_multaggr.c: branchruledata->ratioggain is allocated as block memory but is tried to be freed as normal memory (line 716) which results in an error.


Additionally I have a question about the use of SCIPallocBuffer. The documentation suggest, that buffer memory should only be used when the memory is allocated and freed in the same function. Thus I am wondering, why some structures have "constructors" that use Buffer memory instead of normal memory (e.g.  createConstantAssignment(), createNodedata(), createTcliqueGraph(), initializeMatrix()).


Best Regards,

Tony
