[Soplex] SoPlex segfault when writing dual LP

[Hartmut Henkel]

Dear SoPlex team,

with SoPlex version 6.0.3 [mode: optimized] [precision: 8 byte]
[rational: GMP 6.2.1] [PaPILO: not available] [githash: f900e3d0] there
is a segfault when writing the dual of a rather large LP file (20029
lines, total 817188 bytes). Operation system is debian Linux
6.1.0-9-amd64.

  Reading (real) LP file <soplex.lp> . . .
  Segmentation fault

When i reduce the file to approx. 5000 lines, the segfault vanishes. The
bz2 compressed LP file is 1.5 MByte. I would be glad if you could check
into this, i can send you the file off-list per e-mail.

Best Regards
Hartmut Henkel
