-------- Bug 35810 Comment 12 janus 2010-12-30 13:18:14 CET ---------

Note: realloc_on_assign_2.f03 fails on current trunk when building with
--disable-bootstrap (system compiler: gcc version 4.5.0 20100604
[gcc-4_5-branch revision 160292]):

realloc_on_assign_2.f03: In function ‘test5’:
realloc_on_assign_2.f03:101:0: internal compiler error: in fold_convert_loc, at
fold-const.c:1906


Reduced test case:

program test5
  real, allocatable, dimension (:,:) :: xwrkt
  xwrkt = trs2a2 ()
contains
  function trs2a2 ()
    real, dimension (1:2,1:2) :: trs2a2
    trs2a2 = 0.0
  end function
end

4.5.0 is the system compiler which I use to build the GCC trunk. Since the
failure only appears with --disable-bootstrap that might be relevant.

I still see this problem at r169406.

Can you try again using GCC 4.6.0 r169406 as compiler? (I.e. setting the PATH
and LD_LIBRARY_PATH such that 4.6.0 is used.)

For curiosity, I will try to compile without bootstrapping with
   4.5.1 20101208 [gcc-4_5-branch revision 167585]

However, it looks as if GCC 4.5.0 miscompiles f951; except for not
bootstrapping, there should be no difference between --disable-bootstrap and
not. (Contrary to --enable-checking=release.)

Compiling finished - and works (x86-64-linux); I run f951 under valgrind and it
also did not show any problems.

Setting status to waiting.

Close as fixed as a patch has been committed. I assume, no one can reproduce it
any more?

Dear All,

It was never there for me :-)

Yes, please close it.

Cheers
