I disabled 32bit code maybe this created the following error while building dub :

The detailed error is :

/usr/bin/clang test.o -o test -L/usr/local/lib -lphobos2-ldc -ldruntime-ldc -Wl,--gc-sections -lexecinfo -lpthread -lm -m64
ld: error: undefined hidden symbol: __start___minfo

Try to run clang with -v option and compare with gcc.

I've tracked down the problem to the solution where i specify as linker to use gcc12 instead of a clang/llvm.
The following works.

export CC=clang14
ldc2 --link-defaultlib-shared --gcc=gcc12 ...

But i have no explanation.
