[Couenne] Memory error on couenne?

[Wendel Melo]

Hi experts


I have ran Couenne 0.5.5 on box nonconvex quadratic mixed integer problems
(by AMPL) and I have got some memory errors. I have enforced couenne to run
for, at most,  60 minutes. At the end, I have the following error:


*** Error in `./couenne': double free or corruption (!prev):
0x0000000000c4f6c0 ***
======= Backtrace: =========

./couenne[0x4042d0]
/lib64/libc.so.6(__libc_start_main+0xf5)[0x7fd5bdc72b05]
./couenne[0x4055ba]


I have got this error in two different machines, both running opensuse
linux 64 bits (13.1 and 13.2). Model file and couenne option file used to
generate this error are in attachment.

Does someone know what is happening?
