            Bug ID: 105893
           Summary: RFE: -fanalyzer could check putenv calls
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
            Blocks: 105887
  Target Milestone: ---

See
https://clang.llvm.org/docs/analyzer/checkers.html#alpha-security-cert-pos-34c

I think this might be relatively easy to implement using the analyzer's region
model code.
