It seems to have completely broken as of a CVS update of a few minutes
ago. Most of the time I get no output, but sometimes I get a very very
long row of ZZZZZZ's or sometimes I get
ZZZZZZZZZZZ?Ì?*ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ?Ì?*ZZZZZZZZZ
Repeatedly loading a phpinfo() tends to toggle back and forth. Single
stepping through things looks normal. zif_phpinfo() is getting called and
everything looks fine. So it is something lower level. Output bufferring
changes messing things up?
relevant php.ini settings:
output_buffering = Off
output_handler =
implicit_flush = Off
zlib.output_compression = Off
Same thing happens on a simple echo "Hello World" script.
An strace on that shows:

Rolling back to my libphp4.so build on Aug.13 built with exactly the same
