Description Kaveh Ghazi 2009-11-19 21:20:53 UTC
I seeing failures in gcc.dg/cleanup-13.c on x86_64-unknown-linux-gnu and i686-unknown-linux-gnu with gcc-4.4.3 svn.  E.g.:

FAIL: gcc.dg/cleanup-13.c (test for excess errors)
http://gcc.gnu.org/ml/gcc-testresults/2009-11/msg01708.html

gcc.dg/cleanup-13.c: Assembler messages:
gcc.dg/cleanup-13.c:305: Error: CFI instruction used without previous .cfi_startproc
compiler exited with status 1

The failure only occurs on certain systems.  E.g. on CFARM gcc14 it does NOT occur.  However I do see it on nearly every other CFARM i686 & x86_64 box (e.g. gcc03, gcc09, gcc11, gcc12, gcc13, gcc16, gcc17 all fail).

It probably has to do with older software (gas?)  I seem to recall this came up before and don't recall whether it was fixed somehow or not.  But the error does not occur on mainline.

The uname and as --version output on the box it passes is:
Linux gcc14 2.6.26-2-amd64 #1 SMP Sun Jun 21 04:47:08 UTC 2009 x86_64 GNU/Linux
GNU assembler (GNU Binutils for Debian) 2.18.0.20080103

And if it helps, the uname and as --version output on the failing systems is:
