 The issue is described in the mailing list post

 http://list.coin-or.org/pipermail/ipopt/2009-May/001517.html

 Termination code 11 results if IPOPT (when invoked from AMPL) is compiled
 after running the configure script without arguments. The config.log file
 and the resulting .nl file are attached.

 The following three configure argument configurations has been tried (in
 addition to no arguments):

  - CXXFLAGS='-O3 -g -DNDEBUG' CFLAGS='-O3 -g -DNDEBUG' FFAGS='-O3 -g'
  - CXXFLAGS='-O -g -DNDEBUG' CFLAGS='-O -g -DNDEBUG' FFAGS='-O -g'
  - --enable-debug

 In all these cases the optimization runs fine.

 The tests are run with IPOPT 3.6.1 (which cannot be selected in the list
 below).

Comment:

 Hi Johan,

 Thanks for creating the ticket.

 I had a look at the config.log file, and it seems that you didn't specify
 the flags as you describe in this ticket, you only ran it as "./configure"
 and therefore Ipopt used the default compiler flags:

 CXXFLAGS='-O3 -fomit-frame-pointer -pipe -DNDEBUG -pedantic-errors
 -Wimplicit -Wparentheses -Wreturn-type -Wcast-qual -Wall -Wpointer-arith
 -Wwrite-strings -Wconversion -Wno-unknown-pragmas  '

 I ran your bla.nl example with 3.6.1, and I had no issues, it ran well,
 and valgrind did not detect any errors.  I used the MA27 linear solver
 (from your output it is not clear which one you used - maybe you didn't
 include one and this might be the issues?  Did "make test" work?)

 You are using the GCC 4.3.2 compilers.  I have not tried to compile Ipopt
 with those, and it could be that this is the issue.  I have successfully
 used Ipopt with GCC 4.1.2 and 4.2.1.  As we discussed in the mailing list,
 the segfault happens in a function of the ASL, which is not Ipopt code,
 and you might have to talk to the developer of that software...

 Not sure what I can add at this point...

 Regards,

 Andreas
