>How exactly do i run the IOC from gdb? 

# Go to the directory that has the st.cmd file
cd iocStart/your_ioc_directory

# Check the st.cmd file. It should start with something like
#  "#!../../bin/linuxx86_64/name_of_your_ioc_binary"
#
# That's what you load into GDB

gdb ../../bin/linuxx86_64/name_of_your_ioc_binary

# Then, inside gdb, you start the process with the st.cmd file as input
run st.cmd

# Once it crashes, list the threads
info threads

# Pick one
thread 3

# Get backtrace
bt

# Select some interesting stack frame
frame 2

# print stuff
print some_var
print *some_pointer_var
