Hi, Cristian.

snow and fex are not supported at this point.  We recommend using LBJava and 
the cogcomp-nlp library instead.

Regards,

Mark

Subject: [[Illinois-ml-nlp-users] ] Segmentation fault using SNoW+

I've just downloaded SNoW+ Version 3.2.0, compiled and I haven't been able to
run the test phase, only the train one.

I compiled it using just make, with no errors, only a bunch of warnings
regarding deprecated libraries.

For example, see the output when running the tutorial below. I have tried with
other file formats, with no success. I ran it using strace, and it seems to
fail when reading the network file:

write(1, "Network file: 'tutorial.net'\n", 29Network file: 'tutorial.net'
) = 29
openat(AT_FDCWD, "tutorial.net", O_RDONLY) = 3
read(3, "target 0 0x1p+0 0x1p+0 1858 1407"..., 8191) = 8191
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL} ---
+++ killed by SIGSEGV (core dumped) +++
Segmentation fault (core dumped)

I am running in ubuntu 17.10.

Any help will be appreciated.

The output from command line:
