Error: Decompilation to LLVM IR failed

Start with the retdec-bin2llvmir crash dump and the command output, focusing on the Conditional branch optimization phase for the reported 32-bit ARM ELF DLL. Reproduce the failure if the original input is available, then inspect the conditional branch optimization entry point and relevant tests. Done means the input completes this phase without the decompilation-to-LLVM-IR error and produces the requested output.
