[cfe-dev] 'scan-build ./configure' hang

[Maarten Hoes via cfe-dev]

Hi,


Thanks for the feedback, its appreciated. Well I tried to do some digging,
and it looks to me like this specific configure step is trying to compile
these two small c testcases [1] (config.log mentions 'conftest.c', but I
couldnt find that file on disk).

$ ps -ef | grep ccc-analyzer
gives me :
/bin/sh ./libtool --mode=compile /usr/local/bin/../libexec/ccc-analyzer
conftest1.c -c -o conftest1.lo

Running this on the command line gives me endless lines of this :

Waiting for -c.o.lock to be removed
Waiting for -c.o.lock to be removed

and so on and so on
