480	Unsigned Integers Mishandled	Scott		"There is an error in ngx_string.c::ngx_vslprintf(). At the minimum it behaves incorrectly, at the worst it causes a segfault. It can be triggered by calling ngx_conf_log_error().

ngx_conf_log_error(NGX_LOG_EMERG, cf, 0, ""%u hi"", 20)
Expected output:
nginx: [emerg] 20 hi in <path here>
Actual output:
nginx: [emerg]  hi in <path here>

ngx_conf_log_error(NGX_LOG_EMERG, cf, 0, ""%u %s"", 20, ""hi"");
Expected output:
nginx: [emerg] 20 hi in <path here>
Actual output:
<segfault at nginx_str.c, line 254>

I believe it's related to there not being a case for 'u' at the switch statement that spans lines 230-446. One for 'u' would probably be similar to the 'd' case."	defect	closed	major		nginx-core	1.5.x	invalid			Darwin <node name> 13.0.0 Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64 x86_64	"nginx version: nginx/1.5.8
