[Bug middle-end/18852] New: [3.4 Regression] 8 tests fail: SIGSEGV for stack growth failure

[danglin at gcc dot gnu dot org]

We have the following new fails in the C testsuite:

Running /xxx/gnu/gcc-3.4/gcc/gcc/testsuite/gcc.dg/compat/compat.exp ...

All these fail due SIGSEGVs:

Make sure to have this:

2004-12-04  Richard Henderson  <rth@redhat.com>

	* emit-rtl.c, expr.c, function.c, integrate.c, optabs.c, rtl.h:
	Revert the patches for PR rtl-opt/15289.

Was this before or after RTH applied this patch:
        * emit-rtl.c, expr.c, function.c, integrate.c, optabs.c, rtl.h:
        Revert the patches for PR rtl-opt/15289.

If it was before, then I almost think this is already fixed by this patch.

The last change was:

2004-12-03  Eric Botcazou  <ebotcazou@adacore.com>

	* integrate.c (expand_inline_function): Accept non-CONCAT arguments
	for CONCAT parameters and invoke read_complex_part on them.

I'll retest.

Most probably already fixed, but waiting for the confirmation.
