Hello Everyone,

I'm re-setting up my station on Ubuntu 24.04 and just compiled up Fldigi and Flrig.? For Fldigi, I configured the ./configure stage for compiling with the following:
--
? $ ./configure --build=x86_64-linux-gnu --prefix=/usr '--includedir=${prefix}/include' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' --sysconfdir=/etc --localstatedir
=/var --disable-option-checking --disable-silent-rules '--libdir=${prefix}/lib/x86_64-linux-gnu' --runstatedir=/run --disable-maintainer-mode --disable-dependency-tracking --with-libmbe
dtls LIBMBEDTLS_CFLAGS=-I/usr/include/mbedtls 'LIBMBEDTLS_LIBS=-lmbedtls -lmbedx509 -lmbedcrypto'
--

Everything seems to be running well except if I click on the "Open List" book icon and then click on the "Show active frequencies" dialog bubble icon on the right of the book icon, the waterfall and general UI freezes for about 5 seconds and then I see in the terminal I started it in:
--
*** stack smashing detected ***: terminated
Segmentation fault (core dumped)
--


The stack trace I'm getting from the coredump is as follows:

This is 100% reproducable so I'm curious if other people are seeing this as well.? Any recommendations on a fix?
