Doesn't catch SIGSEGV on Android

[JonasVautherin]

I am trying to use COFFEE_TRY_JNI on Android, but it does not seem to catch the signal. I just copied the coffeecatch source files in my project, and had to remove some of those parts because Android now apparently has them. I only removed what was "duplicated" (keeping the system one and removing the one in coffeecatch.c).

I get the following crash:

Fatal signal 11 (SIGSEGV), code 2, fault addr 0x7969a63cb6 in tid 20990 (DefaultDispatch)

From this code, calling runNative from Java (well, Kotlin actually):

__attribute__ ((noinline))
static void run() {
    char *test = "blah";
    *(test + 1) = 'n';
}

__attribute__ ((noinline))
static void run_protected(JNIEnv *env) {
    COFFEE_TRY_JNI(env, run());
}

JNIEXPORT void JNICALL
Java_com_example_JniApi_00024Companion_runNative(
        JNIEnv *env, jobject thiz) {
    run_protected(env);
}

Am I missing something?

I traced it to this line:

siglongjmp(t->ctx, code);

I get my SIGSEGV right when this is called 🤔.
