-- System Information:
RedHat ES4 (x86_64)
Architecture: x86_64
Kernel: 2.6.9-11.ELsmp


I have php4 compiled with "./configure .. --enable-recode --with-recode ...".


 When I do

$ /usr/bin/php ./test.php
Segmentation fault

and test.php :
<?
  echo recode_string("utf-8..html_4.0","Hello, World !");
?>

I first tought it was a bug on librecode but it works well from the command line :

echo "Hello, World"|recode "utf-8..html_4.0"
Hello, World

I would suggest to use iconv() instead of recode - the recode library is quite a mess.

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

I can not reproduce this with PHP 5.1-dev.
Also, I have GCC-4.0.0, if that makes any difference..

Please don't attach the same backtrace more than once.
I deleted that comment. You reported that your compiler is:
gcc version 3.4.3 20050227 (Red Hat 3.4.3-22.1)

Try this:

# rm config.cache && ./configure --disable-all --disable-cgi --with-recode
# make clean && make 
# run -r 'echo recode_string("utf-8..html_4.0","Hello, World !");'

Thank you for your advice, but still not working. => Segmentation fault. It is possible the problem is only on x86_64 architecture.
 [2005-07-25 20:09 UTC] sniper@php.net
Did you try with the PHP 5.1-dev snapshot? I've tested this in x86_64 (dual opteron machine) and it does NOT crash for me. (I have FC4 installed in it though)
