When a script in php tries to fopen a URL that is long, it will crash on both in cli and FastCGI. This is of course with allow_url_fopen=true. Reproducible: Always Steps to Reproduce: 1.enable allow_url_fopen in php.ini 2.run php in interactive mode (php -a) 3. try the following code : $q = fopen("http://www.google.com/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", 'r'); Actual Results: Crashes, log attached. Expected Results: it should have not crashed.. I've tried this both on x86 at first, but then i had -fomit-frame-pointer in my CFLAGS, so the only thing i saw was what i posted above.In desperation i redid the system in 64bit, but using mostly the same configs and CFLAGS (adjusted to amd64 of course).The actual URL that i use is a normal url, but it contains private data so i refrained in posting it here.Any info on how to resolve this would be welcome.

Thanks for reporting. I need to know the output of your `emerge --info php` as well. Also did you check for/report a bug upstream?
No, i haven't since this seems more like a glibc bug than php, but i can't really pin it down. I went back to x86 (it's faster), but still experience the bug. I'll recompile glibc and php with -O0 and -ggdb, and provide you with a nice backtrace later on.

I can no longer reproduce this, even with 5.3.6. I guess the problem was caused outside of the php package.
Closing Works For Me. I couldn't reproduce this on either x86 or amd64 using php-5.3.6. If you happen to experience the bug again, please try to produce a backtrace and reopen the bug.
