Linking fails with GCC-14 and Clang-19
https://bugs.gentoo.org/946814
ld.lld: error: non-exported symbol 'atexit' in '/usr/lib64/libc_nonshared.a(atexit.oS)' is referenced by DSO '/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../lib64/libdmalloc.so'

/usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld: bin/enblend: hidden symbol 'atexit' in /usr/lib64/libc_nonshared.a(atexit.oS) is referenced by DSO /usr/lib/gcc/x86_64-pc-linux-gnu/14/../../../../x86_64-pc-linux-gnu/bin/ld: final link failed: bad value
More specifically, the exact problem I see is this, in the config.log file produced at configure-time when building the gtick program:
configure:5795: gcc -o conftest -g -O2 conftest.c -ldmalloc -lsndfile -lm >&5
ld: conftest: hidden symbol `atexit' in /gnu/store/yj053cys0724p7vs9kir808x7fivz17m-glibc-2.41/lib/libc_nonshared.a(atexit.oS) is referenced by DSO
ld: final link failed: bad value

But it seems this is not the only issue, as there appear to be issues with the definitions that dmalloc makes when using GCC 14 and glibc 2.41. I've written more details in https://mail.gnu.org/archive/html/gtick-devel/2025-11/msg00001.html, but copying here the errors here:
