1) rb_ary_new cannot be called during allocate function. During allocate
fucntion, the containing object hasn't been marked and rb_ary_new may
invoke gc to collect containing object.
2) The global map should be marked before allocating it. Otherwise it
may be garbage collected.
* Add test
* Remove commented code
* Fix grammer error
We have some special code in wrap_memcpy.c to ensure that we use the
2.2.5 version of memcpy, for compatibility with older versions of glibc.
However, we need to make sure we only attempt to do this when we are
actually building with glibc, so that the code can also build
successfully against other libc implementations such as musl.
This commit adds a __wrap_memcpy function and a linker flag to use that
in place of memcpy for our Ruby gem C extension. This allows us to
always use the 2.2.5 version of memcpy, making it possible to use the
gem on distributions with pre-2.14 versions of glibc.
Before this change:
$ objdump -T protobuf_c.so | grep memcpy
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.3.4 __memcpy_chk
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.14 memcpy
After:
$ objdump -T protobuf_c.so | grep memcpy
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 memcpy
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.3.4 __memcpy_chk
0000000000042450 g DF .text 0000000000000005 Base __wrap_memcpy
This is based on gRPC's solution to a similar problem:
5098508d2d/src/core/lib/support/wrap_memcpy.c
This fixes issue #2783.
