gdb run command fails on mac Mojave

Question

I am using mac Mojave 10.14.5.

Previously I had codesign issue, and resolved from link.

After resolving codesign issue, when I run gdb, the program just stops like below.

For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from CIRMERGE...
Reading symbols from /Users/___/Project/CIRMERGE.dSYM/Contents/Resources/DWARF/CIRMERGE...
(gdb) run
Starting program: /Users/___/Project/CIRMERGE 
[New Thread 0x1703 of process 601]
[New Thread 0x1903 of process 601]

First, I followed the same instruction given in the above link, removing set startup-with-shell enable from ~/.gdbinit. (It was empty and I tried disable option too)

Secondly, I found someone having similar problem with me, so tried to reinstall gdb head, but installing gdb with --HEAD fails like below

==> make

Here is my gdb configuration.

This GDB was configured as follows:
   configure --host=x86_64-apple-darwin18.5.0 --target=x86_64-apple-darwin18.5.0
             --with-auto-load-dir=:${prefix}/share/auto-load

             --disable-source-highlight
             --with-separate-debug-dir=/usr/local/Cellar/gdb/8.3/lib/debug (relocatable)

I am trying to debug my cpp code for hours, so any help would be appreciated.
