hello,
I encounter a strange gcc behavior - it hangs ! this is not happening always.
It can hang sometimes, and sometimes not, with the exact same source
file and gcc command line.
My command is simple, i use several -I parameters (include folders),
-c and -o.. that's it..
gcc -I <folder1> -I <folder2> -I <folder3> -I <folder4> -I <folder5>
-c -o folder6/output.o folder6/source.c
Attached is the end of the strace output, the last line just hangs.. (waitpid).
my gcc version:
$ gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu
--enable-libstdcxx-debug --enable-mpfr --enable-checking=release
i486-linux-gnu
Thread model: posix
gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)
any ideas ?
thank you
sunzir
