Following my commit of the patch for PR29786, I did a further regtest, which produced a good number of fortran testsuite failures. Being late, I put it out of its misery. I reverted to before my patch (r125628) and find that the failures are still there. For example,
$ /irun/bin/gfortran $test/sizeof.f90 /cygdrive/d/svn/trunk/gcc/testsuite/gfortran.dg/sizeof.f90: In function 'check_r eal': /cygdrive/d/svn/trunk/gcc/testsuite/gfortran.dg/sizeof.f90:37: internal compiler error: Segmentation fault f951, run under gdb, runs to completion, so the problem is further towards the backend. I regested earlier last night and all was well (sorry, I did not record the revision #), so the problem has creapt in over a very small number of patches. You will excuse me please if I cannot identify the patch that is responsible - this sort of investigation is just a bit too tedious under Cygwin. I will make one further reversion this morning and will report if I have bracketed the problem. I do not know if there are other gcc regressions. Cheers Paul
