Hi Thomas,
i recently meet below crash within dlopen() related to
toolchain-aarch64_cortex-a53_gcc-13.3.0_musl\gcc-13.3.0 for openwrt.
it seems it is caused by gcc bug related to MACRO ATOMIC_FDE_FAST_PATH
(gdb) bt

....
there are no such issue for the same program built with below gcc-12.3.0
toolchain-aarch64_cortex-a53_gcc-12.3.0_musl\gcc-12.3.0
i am not sure if this is the good way to report gcc issue. (^^)
