Here's the full list of all 37 failures that fail for any reason: FAIL: gcc.dg/analyzer/dot-output.c dg-check-dot dot-output.c.state-purge.dot FAIL: gcc.dg/analyzer/malloc-callbacks.c (test for excess errors) FAIL: gcc.dg/analyzer/pr98969.c (test for warnings, line 17) FAIL: gcc.dg/analyzer/pr98969.c (test for excess errors) FAIL: gcc.dg/analyzer/pr99716-1.c (test for warnings, line 25) FAIL: gcc.dg/analyzer/pr99716-2.c (test for excess errors) FAIL: gcc.dg/analyzer/pr99774-1.c (test for excess errors) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 16) FAIL: gcc.dg/analyzer/sensitive-1.c warning (test for warnings, line 17) FAIL: gcc.dg/analyzer/sensitive-1.c event (test for warnings, line 17) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 23) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 24) FAIL: gcc.dg/analyzer/sensitive-1.c event (test for warnings, line 24) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 30) FAIL: gcc.dg/analyzer/sensitive-1.c warning (test for warnings, line 31) FAIL: gcc.dg/analyzer/sensitive-1.c event (test for warnings, line 31) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 44) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 50) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 55) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 60) FAIL: gcc.dg/analyzer/sensitive-1.c (test for warnings, line 61) FAIL: gcc.dg/analyzer/signal-1.c (test for warnings, line 13) FAIL: gcc.dg/analyzer/signal-1.c (test for warnings, line 25) FAIL: gcc.dg/analyzer/signal-2.c (test for warnings, line 16) FAIL: gcc.dg/analyzer/signal-2.c (test for warnings, line 28) FAIL: gcc.dg/analyzer/signal-3.c (test for warnings, line 10) FAIL: gcc.dg/analyzer/signal-3.c (test for warnings, line 21) FAIL: gcc.dg/analyzer/signal-4a.c (test for warnings, line 15) FAIL: gcc.dg/analyzer/signal-4a.c expected multiline pattern lines 33-75 not found: <snip> FAIL: gcc.dg/analyzer/signal-6.c (test for warnings, line 11) FAIL: gcc.dg/analyzer/signal-6.c (test for warnings, line 16) FAIL: gcc.dg/analyzer/signal-registration-loc.c (test for warnings, line 15) FAIL: gcc.dg/analyzer/signal-registration-loc.c (test for warnings, line 21) FAIL: gcc.dg/analyzer/strndup-1.c (test for excess errors) FAIL: gcc.dg/analyzer/zlib-5.c (test for excess errors) Of those, here is what I diagnosed so far: pr98969.c:9:19: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] * This fails because the function arguments are "long int", and that tries to hold a pointer. It should be uintptr_t or similar. pr98969.c:17:3: warning: double-'free' of '*((struct foo *)(long long int)i).expr' [CWE-415] [-Wanalyzer-double-free] * My guess is that the regex is not right for running under wine, because that shouldn't be an excess error. pr99716-2.c:13:30: warning: implicit declaration of function 'random'; did you mean 'rand'? [-Wimplicit-function-declaration] * The warning is probably right here. The C function is rand(). Where does random() come from? pr99774-1.c:12:14: warning: conflicting types for built-in function 'calloc'; expected 'void *(long long unsigned int, long long unsigned int)' [-Wbuiltin-declaration-mismatch] * size_t issue strndup-1.c:9:13: warning: incompatible implicit declaration of built-in function 'strndup' [-Wbuiltin-declaration-mismatch] * This function doesn't exist on windows. So, either we add it to libmingwex if it isn't already there and then link that library in to the test, or just mark it as unsupported. I'd probably prefer the former, but it's not up to me. zlib-5.c:10:15: warning: conflicting types for built-in function 'strlen'; expected 'long long unsigned int(const char *)' [-Wbuiltin-declaration-mismatch] zlib-5.c:16:14: warning: conflicting types for built-in function 'calloc'; expected 'void *(long long unsigned int, long long unsigned int)' [-Wbuiltin-declaration-mismatch] * size_t issue gcc.dg/analyzer/gzio-3.c: gcc.dg/analyzer/gzio-3a.c: * For some reason, these work. Maybe fread() isn't a builtin? Maybe there's a way to make gcc emit a warning when fread() is redefined differently.
