Thanks for the patch! Every time I look at this code, I see more and more bugs, though, so I tend to clean up as I go. This patch also fixes a couple of cases where we'd fail to deal with an object that we couldn't convert to a string. Unfortunately, I can't compile jsfile.c terribly easily at the moment, so Ralf, could you tell me if this still compiles?
Sorry, I cannot answer this. I've not tried to build the TRUNK version of jsfile.c at all as the newer series of SpiderMonkey have lots of other problems for me, too. I've discovered the bug in the 1.6 series (where it is also existing) as I'm using this version only. The 1.6 series builds fine for me (with and without the patch).
Looking for rs=brendan ;-).
