[Git][cmucl/cmucl][master] 2 commits: Fix a double free detected by the GCC analyzer

Carl Shapiro pushed to branch master at cmucl / cmucl Commits: 729fae26 by Carl Shapiro at 2024-04-25T01:15:17-07:00 Fix a double free detected by the GCC analyzer The obuffer variable contained a pointer to a block of memory freed by realloc(3) if the ERANGE case was executed more than once. Afterward, if the 0 case executed, obuffer would be passed to free(3) causing a double free. This change sets the value of obuffer to buffer immediately after a successful call to realloc(3) ensure it is always NULL or a valid block of memory. - - - - - 7c91087e by Carl Shapiro at 2024-04-25T16:37:26+00:00 Merge branch 'file-author' into 'master' Fix a double free detected by the GCC analyzer See merge request cmucl/cmucl!210 - - - - - 1 changed file: - src/lisp/os-common.c Changes: ===================================== src/lisp/os-common.c ===================================== @@ -762,10 +762,10 @@ os_file_author(const char *path) case ERANGE: /* Buffer is too small, double its size and try again */ size *= 2; - obuffer = (buffer == initial) ?
