Description of problem: Firefox 71.0 crashes when build with PGO Version-Release number of selected component (if applicable): 71.0 Seems to be 71.0 issue only, 70.0 works ok. Both are built with gcc-9.2.1-1.fc31 so it does not look like a gcc regression. backtrace: (gdb) bt #0 NS_ABORT_OOM(unsigned long) (aSize=3661620918) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/base/nsDebugImpl.cpp:604 #1 0x00007ffff03ee48c in nsTSubstring<char>::AllocFailed(unsigned long) (aLength=<optimized out>, this=0x7fffda3fe800) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/string/nsTSubstring.h:1105 #2 nsTSubstring<char>::Assign(nsTSubstringTuple<char> const&) (this=0x7fffda3fe800, aTuple=...) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/string/nsTSubstring.cpp:547 #3 0x00007ffff2f05618 in nsTAutoStringN<char, 64ul>::nsTAutoStringN(nsTSubstringTuple<char> const&) (aTuple=..., this=0x7fffda3fe800, this=<optimized out>, aTuple=...) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/objdir/dist/include/nsTSubstring.h:1349 #4 mozilla::dom::indexedDB::(anonymous namespace)::Cursor::OpenOp::DoIndexKeyDatabaseWork(mozilla::dom::indexedDB::(anonymous namespace)::DatabaseConnection*) (this=0x7fffd7d13760, aConnection=0x7fffd8532100) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/dom/indexedDB/ActorsParent.cpp:26222 #5 0x00007ffff2f05299 in mozilla::dom::indexedDB::(anonymous namespace)::Cursor::OpenOp::DoDatabaseWork(mozilla::dom::indexedDB::(anonymous namespace)::DatabaseConnection*) (this=0x7fffd7d13760, aConnection=0x7fffd8532100) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/dom/indexedDB/ActorsParent.cpp:26326 #6 0x00007ffff2ef3d27 in mozilla::dom::indexedDB::(anonymous namespace)::TransactionDatabaseOperationBase::RunOnConnectionThread() (this=0x7fffd7d13760) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/dom/indexedDB/ActorsParent.cpp:21971 #7 0x00007ffff2ef38ee in mozilla::dom::indexedDB::(anonymous namespace)::TransactionDatabaseOperationBase::Run() (this=0x7fffd7d13760) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/dom/indexedDB/ActorsParent.cpp:22136 #8 0x00007ffff25a067d in nsThread::ProcessNextEvent(bool, bool*) (this=0x7fffd947d280, aMayWait=<optimized out>, aResult=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/threads/nsThread.cpp:1225 #9 0x00007ffff259f4e0 in NS_ProcessNextEvent(nsIThread*, bool) (aThread=<optimized out>, aMayWait=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/threads/nsThreadUtils.cpp:486 #10 0x00007ffff2ef385a in mozilla::SpinEventLoopUntil<> (aThread=0x0, aPredicate=...) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/objdir/dist/include/mozilla/ThreadLocal.h:201 #11 mozilla::dom::indexedDB::(anonymous namespace)::ConnectionPool::ThreadRunnable::Run (this=0x7fffd944d1a0) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/dom/indexedDB/ActorsParent.cpp:12003 #12 mozilla::dom::indexedDB::(anonymous namespace)::ConnectionPool::ThreadRunnable::Run() (this=0x7fffd944d1a0) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/dom/indexedDB/ActorsParent.cpp:11965 #13 0x00007ffff25a067d in nsThread::ProcessNextEvent(bool, bool*) (this=0x7fffd947d280, aMayWait=<optimized out>, aResult=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/threads/nsThread.cpp:1225 #14 0x00007ffff259ebce in NS_ProcessNextEvent(nsIThread*, bool) (aMayWait=true, aThread=0x7fffd947d280) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/threads/nsThreadUtils.cpp:486 #15 mozilla::ipc::MessagePumpForNonMainThreads::Run(base::MessagePump::Delegate*) (this=0x7fffd9564cc0, aDelegate=0x7fffd944e740) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/ipc/glue/MessagePump.cpp:333 #16 0x00007ffff252f3c5 in MessageLoop::RunInternal() (this=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/objdir/dist/include/mozilla/RefPtr.h:305 #17 MessageLoop::RunHandler() (this=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/ipc/chromium/src/base/message_loop.cc:308 #18 MessageLoop::Run() (this=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/ipc/chromium/src/base/message_loop.cc:290 #19 0x00007ffff259c427 in nsThread::ThreadFunc(void*) (aArg=<optimized out>) at /usr/src/debug/firefox-71.0-7.fc31.x86_64/xpcom/threads/nsThread.cpp:458 #20 0x00007ffff77e8b34 in _pt_root () at /lib64/libnspr4.so #21 0x00007ffff7f824e2 in start_thread () at /lib64/libpthread.so.0 #22 0x00007ffff7b50693 in clone () at /lib64/libc.so.6

BTW I think you can paste the nvr's manually into Bodhi web.
(In reply to Jens Petersen from comment #5) > BTW I think you can paste the nvr's manually into Bodhi web. That doesn't work for me, the same result (build not found).
