Bug ID: 100615 Summary: analyzer failed to report leak in rxtxcpu's parse_cpu_list Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: analyzer Assignee: dmalcolm at gcc dot gnu.org Reporter: dmalcolm at gcc dot gnu.org Target Milestone: --- clang's static analyzer found this leak on an error-handling path: https://github.com/stackpath/rxtxcpu/pull/42 which gcc's -fanalyzer failed to report. Looking at the code, I see that the string is passed to strsep and to strtol, which IIRC the analyzer doesn't have special knowledge of (perhaps the analyzer is conservatively assuming that these could free the string?)
