[Valgrind-users] Valgrind hangs on my RHEL-7 box

[Matthew B. <mb...@sa...>]

When I run a real program valgrind hangs on my redhat desktop, however I 
can run on other systems with the same executable.


I ran


valgrind -v -v -v -d -d -d myprog.exe


and it spits out a lot of output and then sits there for many minutes, 
I've let it sit for overnight and no progress.


I'm guessing some system configuration, but I googled and looked around 
and didn't see anything that could cause this..


The last set of output is below, but it doesn't lend any clue to me..
