As OP commented, using Apple's gdb will fix the problem.
Here are instructions to build Apple gdb 6.3.50.20050815-cvs from source on OS 10.9:
NOTE: You will need to install Xcode and set up a build environment. If you have Homebrew installed, run brew doctor
to see if "Your system is ready to brew."
Download the gdb-1822 source tarball from: http://opensource.apple.com/tarballs/gdb/gdb-1822.tar.gz
Extract this into a temporary directory. Open a terminal and cd
into gdb-1822/src
.
Run the configure
script:
./configure --prefix="$HOME/.local/stow/gdb-1822" --disable-debug --disable-dependency-tracking --with-system-readline
(The last three configure arguments are from the homebrew-dupes formula: https://github.com/Homebrew/homebrew-dupes/blob/master/gdb.rb )
Run make:
make make install
Follow the instructions at https://sourceware.org/gdb/wiki/BuildingOnDarwin#Creating_a_certificate to create a gdb-cert code signing certificate.
cd
into $HOME/.local/stow/gdb-1822/bin
and sign the gdb
executable:
codesign -s gdb-cert gdb
cd
into $HOME/.local/stow
and stow the gdb-1822
folder:
stow gdb-1822
Add $HOME/.local/bin
to your PATH
and either restart the terminal or clear Bash's cache to the location of gdb
:
hash -d gdb
