Bug #: 11809
Summary: --coverage writes the .gcda files to the wrong
directory
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P

Hello world + shell script that demonstrates the difference
When a program built with gcc --coverage runs, the .gcda files are written to
(subdirectories of) the directory where the binary resides. When a program
built with clang --coverage runs, the .gcda files are written to
(subdirectories of) the directory where the binary resides, unless the program
called chdir. If the program called chdir, then the files are instead written
to (subdirectories of) the directory to which the program changed.
This means that it's not possible to predict where the .gcda files will end up,
unless the calls to chdir that the program may make can be predicted.
The attached test case builds a hello world program with Clang and GCC and runs
if from different directories, with and without changing directory to
illustrate the difference in behaviour.
This problem was found in r148114.
