I apparently really cocked something up. To remove possible security
implications of having executable stack (a big RedHat no-no) I added
-Wa,--noexecstack to the compilation flags in
bridges/source/cpp_uno/gcc3_linux_intel/makefile.mk but for reasons that escape
me with this change in place the pyuno external code tends to crash at
rReturn = Reference<XInterface > ( pCppI, SAL_NO_ACQUIRE );
in remotebridges/source/bridge/remote_bridge.cxx
when aInstanceName is StarOffice.ComponentContext at
Reference< XInterface > xRet( xBridge->getInstance( aInstanceName ) );
in remotebridges/source/unourl_resolver/unourl_resolver.cxx
when the python code of
resolver.resolve(
"uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext" )
is executed.
Reverting the noexecstack change seems to fix this. It's something to do with
execshield, i.e. alternatively echo 0 > /proc/sys/kernel/exec-shield to disable
execshield also works.
cmc->rene: does this address your similiar sounding pyuno problem ?
cmc->sb: any ideas about this, reverting my change would seem to fix this. That
the right thing to do ?
