2015-08-28erts: Fix hipe bug for maps:merge/2Sverker Eriksson
Add forgotten HIPE_WRAPPER_BIF_DISABLE_GC which could lead to stack-heap overrun if unlucky with the yielding during maps:merge when called by native hipe code.

* vinoski/stderr-eagain/OTP-12942: Handle ERRNO_BLOCK in fd_driver async functions
2015-08-18Handle ERRNO_BLOCK in fd_driver async functionsSteve Vinoski
Several users on erlang-questions have reported problems with recent releases where output to standard_error causes standard_error_sup to die from receiving an unexpected eagain error. In the fd_driver, change the fd_async() function to handle EINTR, and change fd_ready_async() to handle ERRNO_BLOCK. Add a new test to standard_error_SUITE to generate output to standard_error and ensure that standard_error_sup does not die. Thanks to Kota Uenishi for contributing the test case.

* sverk/smp-trace-port-exit-bug/OTP-12901: Teach smp VM how to deal with crash of a linked trace port
2015-08-10Teach smp VM how to deal with crash of a linked trace portSverker Eriksson
Problem: The sys-msg-dispather crashes the VM when trying to send exit signals from the links of the terminating trace port. If try-lock of the linked process fails, a pending exit is scheduled and erts_scheduler_data() is then called to find "my" run queue. But sys-msg-dispatcher is not a scheduler and has no scheduler data, hence SEGV. Fix: If not a scheduler and we cannot get process locks, schedule process in its previous run-queue.

2015-07-08Fix crash when disassembling modules with BIFsBjörn Gustavsson
In a debug-compiled emulator, running erts_debug:df(io) would trigger an assertion failure: 1> erts_debug:df(io). beam/beam_debug.c:301:erts_debug_disassemble_1() Assertion failed: (((funcinfo[0]) & 0x3F) == ((0x0 << 4) | ((0x2 << 2) | 0x3))) Aborted (core dumped) It turns out that the assertion is wrong. It should have been updated in 64ccd8c9b7a7 which made it possible to have stubs for BIFs in the BEAM code for a module. The faulty assertion was only found when when 16317f73f79265 added a smoke test of the BEAM disassembler.

Run erts_debug:df/1 for all loaded modules. On my reasonably fast, modern computer this test case runs in approximately 10 seconds. To avoid spending many minutes running this test case on older computers, limit the running time to 20 seconds. While we are at it, remove all ?line macros.

causing the delete marked object to be left in the table after safe_fixtable(_,false) has returned. This is not super serious as the delete marked object is quite benign and will be deleted at the next unfix operation.
