Incompatibility between MacOS Framework build and Precompiled Header

I try to compile a library as framework using Precompiled Header.

Probleme , precompiled header create a directory "ProjectName"
Step latter: building of framework use "ProjectName" as file... but it's a directory already used

CONFIG += precompile_header
PRECOMPILED_HEADER = ../sources/StdAfx.h ####it is a precompiled headear file

FRAMEWORK_HEADERS.version = Versions
FRAMEWORK_HEADERS.files = $$INCLUDE_HEADERS
FRAMEWORK_HEADERS.path = Headers
QMAKE_BUNDLE_DATA += FRAMEWORK_HEADERS

Build Outptut:

rm: DasHardDevKit: is a directory
make: [DasHardDevKit.framework/DasHardDevKit] Error 1 (ignored)
ld: can't open output file for writing: DasHardDevKit, errno=21 for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [DasHardDevKit.framework/DasHardDevKit] Error 1
08:39:42: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project DevKit (kit: Desktop Qt 5.2.0 clang 64bit)
When executing step 'Make'

WorkArround:
Disable precompiled header seems working

Tested with the both Qt version I have on my machine Qt5.2.0 Qt4.8.4)
