debugallocation_test.sh fails, but make 'check succeeds' on linux

[GoogleCodeExporter]

I was investigating why this test fails on FreeBSD and found that on Linux 
(Mint) it also misbehaves.

'make check' command on Linux succeeds 100%, but when the test 
'debugallocation_test.sh' is run individually, it says it fails Test#15 (like 
on FreeBSD).

That test says that it should pass when output is "@ .*main", but there is no 
word "main" in the output on Linux (same on BSD).

So there are two problems:
1. 'make check' doesn't catch the individual test failure on Linux
2. Test#15 looks for the condition that doesn't exist and fails wrongfully
