Description

nbr 2017-08-06 09:19:28 MSK

При установке пакета LibreOffice-extensions-java LibreOffice на i586 
при запуске libreoffice он падает без сообщений.
Кроме этого, LibreOffice-extensions-java не имеет зависимостей на java.
Экспериментальным путем выявлено, что причиной этого является любое из 
extensions:
SmART,Validator, WatchWindow.
При их удалении libreoffice работает нормально.

Дополнительно.
Если поставить java-1.5.0-sun и выбрать ее для libreoffice,
то все extensions не роняют libreoffice.
Все остальные java не работают.

Похоже, нет
тут не в guard упирается а в неработающую alloca:
Грохается вот тут, на строчке с присвоением нуля:

static void _expand_stack_to(address bottom) {
  address sp;
  size_t size;
  volatile char *p;

  // Adjust bottom to point to the largest address within the same page, it
  // gives us a one-page buffer if alloca() allocates slightly more memory.
  bottom = (address)align_size_down((uintptr_t)bottom, os::Linux::page_size());
  bottom += os::Linux::page_size() - 1;

  // sp might be slightly above current stack pointer; if that's the case, we
  // will alloca() a little more space than necessary, which is OK. Don't use
  // os::current_stack_pointer(), as its result can be slightly below current
  // stack pointer, causing us to not alloca enough to reach "bottom".
  sp = (address)&sp;

  if (sp > bottom) {
    size = sp - bottom;
    p = (volatile char *)alloca(size);
    assert(p != NULL && p <= (volatile char *)bottom, "alloca problem?");
    p[0] = '\0';
  }
}

Попробовал собрать с указанием, что extern alloca
(чтобы ее не пыталось инлайнить) - падения прекратились.

Это как? alloca это вообще не функция, а чёрная магия от компилятора.

Comment 7

nbr 2017-08-07 13:32:53 MSK

Обычно магия, но в принципе это функция.
man 3 alloca
 The  alloca()  function  allocates  size bytes of space in the stack frame of the caller.
       This temporary space is automatically  freed  when  the  function  that  called  alloca()
       returns to its caller.
Normally, gcc(1) translates calls to alloca() with inlined code.
но если ей сказать extern, она, насколько я понял, так делать не будет и будет именно вызывать alloca. Что и надо.

alloca это в принципе не функция.

В gnulib, конечно, есть реализация alloca для обездоленных с помощью malloc и garbage collector'а, но это уже совсем другая история.

> man 3 alloca
>  The  alloca()  function

Это неправда, alloca это __builtin_alloca.
"calls to 'alloca' may become single instructions which adjust the stack directly".  На самом деле не "may", а "will".

В общем, alloca -- это ложный след.

Сабпакета LibreOffice-extensions больше нет, неактуально.
