[SCIP] segmentation fault while using LProw functions

[Naga Venkata Chaitanya Gudapati - nagavenkata.gudapati@studio.unibo.it]

Hello SCIP community,

I am getting a  segmentation fault and it only happens when I am running a particular instance.  This is happening when I try to access rows added by a constraint handler in a function of pricer (adding a new variable). 

I had used SCIP compiled for debugging to identify the issue and have the following output:

	Thread 2 received signal SIGSEGV, Segmentation fault.
	0x000000010093b36d in SCIProwPrint (row=0x106c4fd30, messagehdlr=0x102926cb0, file=0x0) at src/scip/lp.c:5311
	5311	      assert(row->cols[i] != NULL);
	(gdb) strace

I am using scip7.0.1 . Can someone kindly let me know what's the issue here?

Thanks a bunch,
