Created an attachment (id=327592)
ASPX page demonstrating the crash
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_2; en-us)
AppleWebKit/531.21.8 (KHTML, like Gecko) Version/4.0.4 Safari/531.21.10
The XSP process crashes when it comes across an ASPX page with an HTML tag with
an attribute containing an ASP tag whose attributes are surrounded by the same
kind of quotes. (eg, nested double-quotes inside double quoted attributes)
On its own, <asp:Literal id='itemColor' text='red' /> and <asp:Literal
id="itemColor" text="red" /> are fine.
When nested inside an HTML tag, <p style="color: <asp:Literal id='itemColor'
text='red' />;"> and <p style='color: <asp:Literal id="itemColor" text="red"
/>;'> are fine as well.
When using the same quotes in both the ASP tag and the attribute, XSP will
crash citing an illegal hardware instruction: <p style="color: <asp:Literal
id="itemColor" text="red" />;"> <p style='color: <asp:Literal id='itemColor'
text='red' />;'>
Reproducible: Always
Steps to Reproduce:
1. Create aspx page containing <a href="<asp:Literal id="crasher" />">Hello</a>
2. Start new instance of XSP
3. Visit created page
Actual Results:
XSP crashes. In ZSH, "illegal hardware instruction" is printed to the console.
In Bash "Illegal instruction" is printed to the console.
Expected Results:
Page should render, or at least a 500 Error should be displayed.
Tested against OSX 10.5 and 10.6 with the repackaged version of Mono 2.4.2.3
