Subject: Fix the following nasty bug:
X-Git-Tag: RELEASE_0_2~412
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=52ffca0b276ca3cf9c26f36bf9d9bc54ea316630;p=php

Fix the following nasty bug:
- if compile bails out from the middle of compiling, current_buffer is not restored
- if current_buffer is not null, yy_switch_to_buffer will do: *yy_c_buf_p = yy_hold_char; on
the next request
- which would lead to memory corruption on next request
