In addition to the gdFreeFontCache segfault I sent yesterday, here is an
imagettfbbox() crash. I am starting to wonder if we have a basic
incompatibility with the current freetype lib. This is PHP_4_3 on a
Debian box with:
ii libfreetype6-dev 2.1.3+2.1.4rc2-4
FreeType 2 font engine, development files
Program received signal SIGSEGV, Segmentation fault.
