Code Issues Releases Activity

[ARM] This patch fix some testsuite issues on ARM:

Browse source 
- Gtest-bt: like on x86/-64, the stack size passed to sigaltstack() is
  too small for ARM thus causing segmentation fault due to stack
  overflow.

- Gtest-dyn1: code size definition of dynamic function (template()) on
  testcase is too big for ARM architecture so memcpy() reads invalid
  memory causing random crashes (segmentation fault). A better
  solution would be to compile the function in a separate binary,
  mmap() it and memcpy() from it instead, so maximum size is known for
  sure.

- check-name-space.in: fix some "bashisms", it causes the script to
  fail to run on N8XX's busybox shell.
