In a large application, a certain routine from the UMFPACK library is
miscompiled when -O is specified. Without optimisation, the routine works
fine. This triggers an assertion failure in the code.
I use gcc (GCC) 4.1.0 20051030 (experimental). The problem can be reproduced
with the attached source files. To see the error, compile them with
/gcc/bin/gcc -g -O -o umfpack-bug umfpack-call.c umf_analyze.i
umf_apply_order.i umf_order_front_tree.i umf_dump.i
When run, the executable aborts with an assertion failure:
/Users/eschnett/Calpha/arrangements/AEIThorns/AHFinderDirect/src/sparse-matrix/umfpack/umf_analyze.c:500:
failed assertion `parent == j+1'
Abort trap (core dumped)
To make the error go away, omit the "-O" option. In this case, the executable
runs without producing any output.
The error seems to be the following. The routine UMF_analyze contains a large
loop in which the local variable pdest is changed. In the next iteration,
pdest is reset to the value it had before the loop. This happens only for
local variables, not for static or global variables.
The error seems to be specific to powerpc; it does not happen on i386.
gcc 3.3 does not have this problem.

It does fail for me on i686 with 4.1.0 20051026.

A little more info, umf_analyze.i is being miscompiled. I don't know which one
yet.

-O1 -fno-tree-ccp -fno-tree-store-ccp -fno-tree-dominator-opts works (maybe
this will give a hint on how to reduce the issue).

I would like to identify the cause of this problem. Would it help if I tracked
down the patch number that caused this problem? Andrew, do you have an
automated system to do that, or is someone already doing it? Otherwise I would
try that with a small script. But it seems to take a long time to do that, so
I wouldn't want to waste the effort.

For now, I am trying to get the size of umf_analyze down by removing the
unnecessary prototypes, beautifying the code, etc...
