SEGV on static build php >= 8.3 with gettext #17735
Comments

can t reproduce with bare php however having experienced with static-php-cli in the past, I ll have a look at this soon-ish. |
|
Can reproduce with 8.3.16 indeed (static cli version only). Looking. |
|
Spent a bit of time, it only segfault from 8.3.0 indeed, 8.2.27 is fine. I had few questions.
What was the setting for the last time it did worked ? e.g. PHP version/static-cli-php version itself? was the musl toolchain the same ? |

Thank you for your long time. I just compared the code carefully two months ago. The problem may be in the gettext build command. # 2 month ago
$extra = $this->builder->getLib('ncurses') ? ('--with-libncurses-prefix=' . BUILD_ROOT_PATH . ' ') : '';
$extra .= $this->builder->getLib('libxml2') ? ('--with-libxml2-prefix=' . BUILD_ROOT_PATH . ' ') : '';
shell()->cd($this->source_dir)
->setEnv(['CFLAGS' => $this->getLibExtraCFlags(), 'LDFLAGS' => $this->getLibExtraLdFlags(), 'LIBS' => $this->getLibExtraLibs()])
->execWithEnv(
'./configure ' .
'--enable-static ' .
'--disable-shared ' .
'--disable-java ' .
'--disable-c+ ' .
$extra .
'--with-libiconv-prefix=' . BUILD_ROOT_PATH . ' ' .
'--prefix=' . BUILD_ROOT_PATH
)
->execWithEnv('make clean')
->execWithEnv("make -j{$this->builder->concurrency}")
->execWithEnv('make install');# now
$extra = $this->builder->getLib('ncurses') ? ('--with-libncurses-prefix=' . BUILD_ROOT_PATH . ' ') : '';
$extra .= $this->builder->getLib('libxml2') ? ('--with-libxml2-prefix=' . BUILD_ROOT_PATH . ' ') : '';
shell()->cd($this->source_dir)
->setEnv(['CFLAGS' => $this->getLibExtraCFlags(), 'LDFLAGS' => $this->getLibExtraLdFlags(), 'LIBS' => $this->getLibExtraLibs()])
->execWithEnv(
'./configure ' .
'--enable-static ' .
'--disable-shared ' .
'--disable-java ' .
'--disable-c+ ' .
$extra .
'--with-included-gettext ' .
'--with-libiconv-prefix=' . BUILD_ROOT_PATH . ' ' .
'--prefix=' . BUILD_ROOT_PATH
)
->execWithEnv('make clean')
->execWithEnv("make -j{$this->builder->concurrency}")
->execWithEnv('make install');The only thing that seems to have changed in the past two months is So the conclusion should be that the built-in GNU gettext is now included, which causes the segmentation fault. In other words, either there is a problem with gettext itself, or I am missing some necessary compilation parameters or patches. I'll dig a little deeper locally, and let me know if there are any details I've overlooked. |

I finally figured it out. In short, libintl/gettext was not built in multithreaded mode correctly. I ended up compiling the gettext library with I didn't look up how to build it for official or common Linux distributions though, I can only confirm that this method works for static-php-cli. |

Good to know ! |

Additional Information
The PHP build is from source and gettext is statically linked. This bug did not exist 2 months ago and only affected PHP 8.3 and 8.4.

This is static-php-cli build log that shows which build command used. If more details need, I'd like to show.

I'm not sure if it's a problem with PHP or gettext itself, I'll be happy to follow up with static-php-cli if any clues are available.
