Slightly reduced test case - needs now only FoX
Reduced test case -- still pretty large, but now only depends on FoX. Use
similarly to PR 41772:
wget http://www.uszla.me.uk/FoX/source/FoX-4.0.4.tar.gz
tar xfz FoX-4.0.4.tar.gz
cd FoX-4.0.4 && ./configure FC=gfortran && make -j4
gfortran -Iobjs/finclude fox.f90 objs/lib/libFoX_{dom,utils,sax,common,fsys}.a
./a.out
In order to see better what goes wrong, patch dom/m_dom_dom.F90's removeChild
by adding the PRINT statements:
do i = 1, size(arg%childNodes%nodes)
print *, 'removeChild: Walking list, i = ', i
if (associated(arg%childNodes%nodes(i)%this, oldChild)) then
print *, 'removeChild: Walking list, fount it, i_t = ', i_t
The gfortran output is then:
removeChild: Walking list, i = 1
[...]
removeChild: Walking list, i = 9
NOT_FOUND_ERR
While g95/NAG f95 have:
removeChild: Walking list, i = 1
[...]
removeChild: Walking list, fount it, i_t = 4
[...]
removeChild: Walking list, i = 9
FoX_NODE_IS_NULL
(Afterwards, all core dump. The result that it = 4 is found, can also be seen
with the full program, where no segfault occurs.)
The needed input.xml can be found in attachment 18846 of PR 41772
