Hi all, I am using WebKit-r51075, the lastest WebKit version. now the question: 1, line 1354 of RecordSpan() in JavaScriptCore/wtf/FastMalloc.cpp : if (span->length > 1) 2, "span->length" is type "uintptr_t", while "1" is int, are there any error potentials for this compare? 3, I run GtkLauncher on my embedded linux platform and got "signal SIGBUS" here 4, the error comes from byte-padding mostly, so, would the expression bring such issue here? 5, if it is, how to fix then? Thanks in Advance, Tony Wang
