When a literal was used from several processes, the literal would
be dumped in only one of the processes. The other processes
that referenced the literals would have incomplete heap data.
|
|
Maps would be dumped as the atom 'undefined', which is
not very informative.
|
|
Writing of crash dumps were done using unbuffered IO. This
is slow since many small writes are done.
Use a FILE* with an allocated buffer to obtain buffered IO.
I wrote a small test program that created 50000 binaries of 200 bytes
each and then created a crash dump. The crash dumping was an order of
magnitude faster with buffered IO than without.

Bifs that are called through the export entry
using i_call_last could have their cp set to
return_trace, just like any other call. So we
have to unwind the trace stack to get the correct
cp. Not doing this creates a lot of issues for
fprof.

We can't just leave it in queue with dist_ext=NULL.
Two symptoms seen:
1. 'receive' trying to deref dist_ext as NULL.
2. GC think it's a term and put THE_NON_VALUE in root set.

The byte_offset of sub-binaries wasn't taken into account for
ProcBins, subtly ruining the results. The test suite didn't catch
it since it didn't check for sub-binaries in particular, and only
checked for equality between variations -- not whether the output
was equal to the input.

sverker/on_load-on_load-bug/OTP-14612
|
|
Symptom: VM crash when erlang:trace_pattern(on_load, ..) is set and
module with -on_load is loaded.
Problem: Tracing and -on_load clash in their use of Export.beam[1]
Solution: Do not do call set_default_trace_pattern in finish_loading_1
for modules with -on_load. finish_after_on_load_2 will do that anyway.

Besides being noisy, they were already defined by a global Unix-
specific header, causing the Windows build to fail if one forgot to
define them.
