Responsible Changed From-To: freebsd-ports-bugs->clement Over to maintainer of www/apache2, although it's not completely clear if that is where the problem lies. Responsible Changed From-To: clement->ale This is a pure php problem actually. Apache segfaults because hash_insert() call is mysql one, not recode one. Problem desappears when you remove mysql extension. Both libraries export hash_insert as global symbol. root@crashbox# nm /usr/local/lib/librecode.so | grep hash_ins 00035550 T hash_insert root@crashbox# nm /usr/local/lib/mysql/libmysqlclient.so.12 | grep hash_ins 00012484 T hash_insert Runtime linker use the first occurence of hash_insert (per default it's mysql one). Over to ale, I don't really know how to fix it... State Changed From-To: open->closed Read the warnings at http://www.php.net/recode |
If mod_php4 loads recode.so(GNU recode library) as its extension, apache2 cannot graceful restart, neither using apachectl or kill -HUP. If this extension is removed, things go perfectly. Below is the backtrace: (I dont know why recode.so will try to access mysql library, maybe that's the problem) (gdb) where #0 0x283e019f in kill () from /lib/libc.so.6 #1 0x283d3ca6 in raise () from /lib/libc.so.6 #2 0x284540d2 in abort () from /lib/libc.so.6 #3 0x283ef55c in _UTF8_wcsnrtombs () from /lib/libc.so.6 #4 0x283ef5a8 in _UTF8_wcsnrtombs () from /lib/libc.so.6 #5 0x283f026b in _UTF8_wcsnrtombs () from /lib/libc.so.6 #6 0x283f0842 in _UTF8_wcsnrtombs () from /lib/libc.so.6 #7 0x283f09bf in free () from /lib/libc.so.6 #8 0x288bc851 in my_no_flags_free () from /usr/local/lib/mysql/libmysqlclient.so.14 #9 0x288c27a9 in delete_dynamic () from /usr/local/lib/mysql/libmysqlclient.so.14 #10 0x288c40cc in hash_free () from /usr/local/lib/mysql/libmysqlclient.so.14 #11 0x28b55711 in recode_delete_outer () from /usr/local/lib/librecode.so.3 #12 0x28a26ed7 in zm_shutdown_recode (type=1, module_number=14) at /usr/ports/converters/php4-recode/work/php-4.3.10/ext/recode/recode.c:113 #13 0x285b01bd in ??
