 Posted: Thu May 24, 2007 12:03 am Post subject: [SOLVED] PHP 5.2.2 + Apache2.058 + MySQL5.0.40 segfault |
 |
|
Hi there. I'm experiencing segfaults on apache every time one of my websites tries to access any database on the mysql server (for example, SquirreMail). Otherwise, they work just fine. I've already trying rebuilding the apps several times, adding and removing flags on use and make.conf, removing files from php, and some solutions on various posts, downgrading apache, php and mysql, but I couldnt find anything similar, nor a fix.
This is my make.conf:
| Code: | CFLAGS="-O3 -march=pentium3 -falign-functions=4 -funroll-loops -pipe"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"

My first port of call would be to run "revdep-rebuild". Since the problem is specific to accessing the MySQL databases, by guess would be that this is where the problem lies.
What happens is that mysql provides a library which other applications then use to talk to it. However, if MySQL is upgraded and the library changes significantly, it will start causing problems unless the programs that use the library are recompiled to work with the new version. revdep-rebuild basically goes through the installed packages, checking what libraries they use, and if it thinks they need it, lists them for recompiling.
Tip: You can use "revdep-rebuild -p" to have revdep-rebuild tell you what it will do instead of actually doing it. |

Thanks for your answer! Already done it.Other than finding missing libraries for X (wich I dont use), it doesnt recompile anything related with MySQL, PHP nor apache. |

If this is the same thing I'm having, it's entirely PHP.
The behaviour I'm seeing (after upgrading to 5.2) is:
- Any PHP script that contains a <?php tag of any kind segfaults the apache child process
- Any PHP script that contains ONLY html (no <?php tag) works fine.
I can do this with the most simple, brain-dead script, and it still causes the problem.
And (dammit!), PHP 5.1 is now on the security advisory list.... Sigh....
No-one has seen any solutions? |

SOLVED!
After much digging, I managed to find references to bad CFLAGS causing this problem.
Apparently "-funroll-loops" in your CFLAGS will cause this.
Specifically, I removed:
| Code: | | -funroll-loops -mmmx -m3dnow |
from my CFLAGS, and the problem no longer seems to occur! |

| Solved! Added O2 and removed -funroll-loops from cflags. Thank you all for your support. |
