- • Fixing the PDB string list termination relies on reverse-engineering or observed behavior due to the lack of a formal specification, potentially leading to compatibility issues with other PDB tools.

Re: [PATCH] ld/pdb: Terminate the string list in S_ENVBLOCK
Mark Harmstone is reviewing patches related to terminating string lists in S_ENVBLOCK symbols within the PDB format. Oleg Tolmatcev has provided an explanation and a link to LLVM’s implementation, which explicitly terminates the list with a zero byte. Harmstone points out the lack of a formal PDB specification and asks Tolmatcev to confirm if the observed behavior is also present in Microsoft’s cvdump.exe to ensure the fix is correct and not specific to LLVM’s implementation.
