escape_expand() is broken?
Message 1 in thread
Hey Guys,
Anyone else having problems with escape_expand? Doing this:
message($$escape_expand("Hello \n\t world!"))
gives me this:
Project MESSAGE: Hello
worrrl
The newline, "\n", and tab, "\t", are properly formatted for any variation I
tried, but the output gets corrupted. Haven't found anything on this, could
someone please confirm.
Thanks,
Pete

No one else has run in to this? Could a kind soul please help me check?
Put this line in a qmake project file;
message($$escape_expand("Hello \n\t world!"))
and run
qmake-qt4 myproject.pro
and check the output.
I'm running qt 4.3.1 on ubuntu. qmake-qt4 -v says:
QMake version 2.01a
Using Qt version 4.3.1
Thanks,
Pete

I can confirm this on PLD Linux Box with qt-4.3.0.

in qt 4.3.1 sources, have a look into qmake/project.cpp:
case E_ESCAPE_EXPAND: {
[...]
memcpy(i_data+x+1, i_data+x+2, i_len-x);
[...]
They are using a memcpy here instead of memmove (which is needed because
of the overlapping memory areas).
Cheers,
Peter
P.S. i leave it to you to report this to qt-bugs@xxxxxxxxxxxxx
