Summary: Bus error with -O4 on memory deallocation
Product: tools
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P2
Component: llvm-gcc
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Experiencing an easily reproducible Bus Error on memory deallocation with the
PHP project on Darwin with the O4 compiler flag (or with -flto).
1) grab the php source (http://snaps.php.net)
2) tar xjvf php5.3[...].tar.bz2
3) cd php5.3[...]
4) ./configure --enable-debug --enable-cli --disable-all --without-sqlite3
5) make && make install && make test
The symbol in question is zend_llist_destroy. I would attach the bugpoint
report however it is too large and given the issue is easy to reproduce it
seems less practical.
I'll leave it to the community to determine the real severity of this bug.
