Operating system: Solaris 8 Intel MU6
PHP version:      4.1.0
PHP Bug Type:     Dynamic loading
Bug description:  PHP (Apache DSO) crashes on startup

When PHP 4.1.0 is compiled on Solaris 8 x86 with gcc 2.95.3 (Solaris ld,
GNU as) with GD 1.5 (for GIF support), it seg faults on Apache startup. A
backtrace with GDB shows the seg fault occurs in dlerror() during
initialization of libthread.so.

Setting LD_PRELOAD to preload libthread.so makes the seg fault go away, but
now I get the message:

Cannot load /usr/local/apache/libexec/libphp4.so into server: ld.so.1:
/usr/local/apache/bin/httpd: fatal: relocation error: file
/usr/local/apache/libexec/libphp4.so: symbol gdImageColorResolve:
referenced symbol not found

I managed to resolve the problem by applying the following patch to
ext/gd/php_gd.h:

*** php_gd.h~   Fri Aug 24 13:07:07 2001
--- php_gd.h    Tue Dec 11 17:42:38 2001

  #endif
  PHP_FUNCTION(imagearc);
  PHP_FUNCTION(imagechar);
