…e.so (#1107) In Windows Subsystem for Linux, libd3d12.so is a shim that dlopen's libd3d12core.so and uses dlsym to resolve D3D12GetInterface. Due to ELF symbol interposition, dlsym may resolve back to libd3d12.so's own export, causing infinite recursion and a stack overflow. Example: ``` ❯ ./api-query PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug. Stack dump: 0. Program arguments: ./api-query #0 0x00005555556e960b llvm::sys::PrintStackTrace(llvm::raw_ostream&, int) /home/icohedron/hlsl-dev/llvm-project/llvm/lib/Support/Unix/Signals.inc:880:13 #1 0x00005555556e70f5 llvm::sys::RunSignalHandlers() /home/icohedron/hlsl-dev/llvm-project/llvm/lib/Support/Signals.cpp:109:18 #2 0x00005555556ea45a SignalHandler(int, siginfo_t*, void*) /home/icohedron/hlsl-dev/llvm-project/llvm/lib/Support/Unix/Signals.inc:448:38 #3 0x00007ffff7442790 __restore_rt (/nix/store/jms7zxzm7w1whczwny5m3gkgdjghmi2r-glibc-2.42-51/lib/libc.so.6+0x42790) #4 0x00007ffff7df4a21 (/usr/lib/wsl/lib/libd3d12.so+0xb7a21) #5 0x00007ffff7df6b6a (/usr/lib/wsl/lib/libd3d12.so+0xb9b6a) #6 0x00007ffff7df8ac6 D3D12GetInterface (/usr/lib/wsl/lib/libd3d12.so+0xbbac6) #7 0x00007ffff7df8adf D3D12GetInterface (/usr/lib/wsl/lib/libd3d12.so+0xbbadf) ... #254 0x00007ffff7df8adf D3D12GetInterface (/usr/lib/wsl/lib/libd3d12.so+0xbbadf) #255 0x00007ffff7df8adf D3D12GetInterface (/usr/lib/wsl/lib/libd3d12.so+0xbbadf) Failed to query D3D info queue Segmentation fault (core dumped) ./api-query ``` This PR fixes the issue by explicitly linking libd3d12core.so before libd3d12.so so it appears first in the global symbol table.
