One more critical problem in 5.4 View as Markdown

the main difference is php_sprintf
in 5.3 it calls OG(php_body_write) which points to php_default_output_func at
tha point.
in 5.4 it calls php_output_write, which writes output via SAPI.

Hi Stas,

We've just found one more critical problem in 5.4.

Apache/PHP crashes in case of error on startup, when
display_startup_errors=1. It's probably related to new output API.

I afraid it may affect many php users.

In 5.3 SAPI functions were not called for startup errors.

I'm not going to fix it myself.

Thanks. Dmitry.

Hi Stas,

Thank you, I'm already looking into it.

OK, thanks. Looks like we'd be needing another RC then. Let's fix this
one and the FILE crash in that case.
