Reduced a little further, showing that bucketCount gets corrupted:
----
import core.stdc.stdio: printf;

pragma(inline, false) void[] calloc_(size_t bc) nothrow pure
{
    debug printf("%x\n", bc); /* prints "ffffffff", should print "1" */
    return [];
}

void main()
{
    {
        File file_;
        nop();
    }

    auto scache = StringCache(1);
}

struct File
{
    ~this() {}
}

void nop() {}

struct StringCache
{
    this(size_t bucketCount)
    {
        buckets = calloc_(bucketCount)[0 .. bucketCount];
        printf("");
    }

    void[] buckets;
}

And further, removing -inline from the equation (still needs -release -O):
----
import core.stdc.stdio: printf;

void[] calloc_(size_t bc) nothrow pure
{
    debug printf("%x\n", bc); /* prints "ffffffff", should print "1" */
    return [];
}

void main()
{
    try nop();
    finally {}

    StringCache scache;
    size_t bucketCount = 1;
    void[]* buckets = &scache.buckets;
    *buckets = calloc_(bucketCount)[0 .. bucketCount];
    printf("");
}

void nop() {}

struct StringCache
{
    void[] buckets;
}

I diggered and found https://github.com/D-Programming-Language/dmd/pull/4909 to be the culprit.

FWIW, the following patch fixes it for me:
