Error: Failed to read Mach-O binary

Hi there. Suddenly faced a problem when tried to install a formula from my own tap:

This is a precompiled binary, and, well, I’m not very sure it’s not a bug in Brew itself, because every tool I picked to test the binary says the opposite:

λ file /usr/local/Cellar/jtool2/2.0_3/bin/jtool2
/usr/local/Cellar/jtool2/2.0_3/bin/jtool2: Mach-O universal binary with 4 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64]

Well, every tool except for objdump, but I don’t think that’s a bug at all, let alone a cause.

λ objdump -a  /usr/local/Cellar/jtool2/2.0_3/bin/jtool2
In archive /usr/local/Cellar/jtool2/2.0_3/bin/jtool2:

objdump: bfd_mach_o_scan: unknown architecture 0x200000c/0x1

Should I open an issue on Homebrew/brew?
