Description Kedar Sovani 2009-10-30 08:49:32 EDT
When the "php" binary is executed to create phar.php, an alignment error is encountered thus causing the build to fail.

Created attachment 366794 [details] proposed fix proposed fix
Comment 2 Joe Orton 2009-10-30 09:48:46 EDT
- (z)->value = (v)->value; \ + memcpy(&(z)->value, &(v)->value, sizeof((z)->value)); \ those are logically equivalent in C, surely? Where's the alignment issue occurring with the use of this macro?
Comment 3 Jitesh Shah 2009-10-30 11:51:08 EDT
If (z)->value or (v)->value is improperly aligned, the first statement will fault. But, memcpy falls back to a byte-by-byte copy, thus, eliminating any unaligned accesses.

http://lecs.cs.ucla.edu/wiki/index.php/XScale_alignment http://netwinder.osuosl.org/users/b/brianbr/public_html/alignment.html#q3 ARM expects pointers/words are aligned on word boundary. The pointer values that are passed to this assignment are now aligned on such a boundary, thus causing the problems. Here is the failed log: http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=75564 Here is the successful build after applying this patch: http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=75686
Comment 5 Bug Zapper 2009-11-16 09:41:04 EST
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 6 Bug Zapper 2010-11-04 02:58:50 EDT
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 7 Bug Zapper 2010-12-03 22:36:02 EST
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
