linker string sharing causes corruption

ghc found a "00" in some unrelated code
and the "0000000000000000000000000000000000000000" in the dummySpace
and then it shared the last 3 bytes (the 00 and terminating null) between both strings

embedding a git rev within the binary, then changed the "00" in unrelated code

if (BIO_write(bp, "00", 2) <= 0)
after letting ghidra finish decompiling, i found that the "00" is shared between 4 places, some haskell code, and some openssl C code!

i suspect this is a linker bug, not a ghc bug
