HttpHeadersExceededSizeLimit when authenticating oauth.

I get the following when I attempt to authorize with bork. It seems to originate from src/network/twitch/auth.zig and is related to the following lines of code:

bork/src/network/twitch/auth.zig

Lines 158 to 163 in c0baab9

    
           var header_buffer: [1024]u8 = undefined; 
        
           accept: while (true) { 
        
               var res = try server.accept(.{ 
        
                   .allocator = gpa, 
        
                   .header_strategy = .{ .static = &header_buffer }, 
        
               });

Current zig header_strategy defaults to dynamic at 8192:

    header_strategy: HeaderStrategy = .{ .dynamic = 8192 },

When I simply comment out header_buffer being passed in I successfully am able to handle the headers, but then I get the following error:

Waiting...
Authenticating with Twitch...
fish: Job 1, 'bork start' terminated by signal SIGSEGV (Address boundary error)

Changing header_buffer to 2048 successfully fit my headers and avoided my address boundary error! I'll push a PR and link this issue with the change. Feel free to decline the PR if you prefer another approach.

Would love to see the segfault being investigated a little. Merged the PR in the meantime.

//var header_buffer: [2048]u8 = undefined;
            //.header_strategy = .{ .static = &header_buffer },

This is the stacktrace if the code doesn't use an explicit header_strategy:
