From cd2eaf2a33e42d9842ac6e6bdb50a14c8d0553ad Mon Sep 17 00:00:00 2001 From: k0kubun Date: Tue, 24 Jul 2018 15:40:05 +0000 Subject: mjit.c: handle memory allocation failure which was missing in r64033. Prior to r64033, memory allocation failure had been checked by TRY_WITH_GC and handled by rb_memerror. But calling rb_memerror on MJIT worker is problematic since it does EC_JUMP_TAG in the end. Threads except Ruby's main thread must not use it. mjit_compile.c: ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64037 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- mjit.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'mjit.c') diff --git a/mjit.c b/mjit.c index 473f60ccb4..eca995742b 100644 --- a/mjit.c +++ b/mjit.c @@ -334,7 +334,8 @@ form_args(int num, ...) for (i = len = 0; i < num; i++) { args = va_arg(argp, char **); n = args_len(args); - res = (char **)realloc(res, sizeof(char *) * (len + n + 1)); + if ((res = (char **)realloc(res, sizeof(char *) * (len + n + 1))) == NULL) + return NULL; MEMCPY(res + len, args, char *, n + 1); len += n; } @@ -767,6 +768,8 @@ compile_c_to_so(const char *c_file, const char *so_file) #ifdef _MSC_VER solen = strlen(so_file); files[0] = p = (char *)malloc(sizeof(char) * (rb_strlen_lit("-Fe") + solen + 1)); + if (p == NULL) + return FALSE; p = append_lit(p, "-Fe"); p = append_str2(p, so_file, solen); *p = '\0'; -- cgit v1.2.3
