Jed, but why do I get in line 3003 in src/mat/impls/aij/seq/aij.c at
all? As far as understand, if I don't pass nnz (NULL in C/C++ or
PETSC_NULL in fortran) I have to avoid this loop in aij.c code. <br></div></blockquote><div><br></div><div>This is the problem. Fortran does not allow this kind of flexible checking, so there are different kinds of "NULL"s. You</div>

I don't have much experience with valgrind. Could you provide me

Thanks a lot for your help.<div><div></div><div class="h5"><br>

Then I traced it under debugger both on Windows and Linux and
realized that it doesn't crash under Windows only by luck. <br>
<br>
The call stack if the folowing:<br>
[C] MatSeqAIJSetPreallocation_SeqAIJ, FP=7fffb4513880<br>
[C] MatCreateSeqAIJ, FP=7fffb4513900<br>
[C] matcreateseqaij_, FP=7fffb4513960<br>
[F90] MODELING_MOD`modeling, FP=7fffb4517740<br>
<br>
As far as I understand after debugging the problem is that nnz
in MatSeqAIJSetPreallocation isn't 0 and I go through this
code:<br>
if (nnz) {<br>
for (i=0; i<B->rmap->n; i++) {<br>
if (nnz[i] < 0)
SETERRQ2(PETSC_ERR_ARG_OUTOFRANGE,"nnz cannot be less than 0:
local row %d value %d",i,nnz[i]);<br>
if (nnz[i] > B->cmap->n)
SETERRQ3(PETSC_ERR_ARG_OUTOFRANGE,"nnz cannot be greater than
row length: local row %d value %d rowlength
%d",i,nnz[i],B->cmap->n);<br>
}<br>
}<br>
<br>
But why is nnz nonzero? I passed PETSC_NULL. It seems like
macros CHKFORTRANNULLINTEGER in matcreateseqaij_ should set
it to zero, but it doesn't. <br>
