zig compiler segfaulting

[fleet jolt]

const nt = @import("nt.zig");

export fn _start(inData: [*c]u64) callconv(.Win64) void {
    const PsInitialSystemProcess: u64 = inData[8];
    
    while(true) {
        var currentEntry = PsInitialSystemProcess;

        while(true) {
            const list: nt.PLIST_ENTRY = @ptrFromInt(currentEntry + 0x2F0);
            currentEntry = @intFromPtr(list.*.Flink) - 0x2F0;    
            if (currentEntry == PsInitialSystemProcess) break;
        }
    }
}

Compiling this code with
zig build-exe main.zig -O ReleaseSmall -fstrip -fomit-frame-pointer -fsingle-threaded -fno-stack-check -fno-unwind-tables -fPIC -target x86_64-freestanding crashes the zig compiler. its only output is the
Segmentation fault (core dumped)

currentEntry and PsInitialSystemProcess point to EPROCESS structures

0x2F0 is the offset to the next eprocess list entry

Im compiling on debian bookworm on master

const nt = @import("nt.zig");

export fn _start(inData: [*c]u64) callconv(.Win64) void {
    const PsInitialSystemProcess: u64 = inData[8];
    
    while(true) {
        var currentEntry = PsInitialSystemProcess;

        while(true) {
            const forwardLink: *u64 = @ptrFromInt(currentEntry + 0x2F0);
            currentEntry = forwardLink.* - 0x2F0;    
            if (currentEntry == PsInitialSystemProcess) break;
        }
    }
}

but this seems to work?
