--- Comment #2 from Ori Livneh <[email protected]> --- (Documenting my baby-steps.) I run gdb like this: $ TRACE=bcinterp:3 HPHP_TRACE_FILE=/tmp/hphp.log gdb -ex run --args /usr/local/bin/hhvm /srv/mediawiki/tests/parserTests.php --file=/srv/mediawiki/68422.txt And I see: hhvm: /srv/hhvm-dev/hphp/runtime/base/ref-data.h:118: HPHP::Cell* HPHP::RefData::tv(): Assertion `m_magic == Magic::kMagic' failed. The relevant frame looks like this one: #4 0x0000000001f76289 in HPHP::RefData::tv (this=0x7fffe8759c50) at /srv/hhvm-dev/hphp/runtime/base/ref-data.h:118 So: (gdb) frame 4 #4 0x0000000001f76289 in HPHP::RefData::tv (this=0x7fffe8759c50) at /srv/hhvm-dev/hphp/runtime/base/ref-data.h:118 118 assert(m_magic == Magic::kMagic); (gdb) p m_tv->m_data.pobj $1 = (HPHP::ObjectData *) 0x6a6a6a6a6a6a6a6a 0x6a6a6a6a is typical of memory freed by the smart allocator, which suggests that this is a use-after free bug. -- You are receiving this mail because: You are the assignee for the bug.
