return error code 139 when i am trying to launch c-compiler for symbolic calculation on MSSM model

Unfortunately I can not reproduce this bug. In my computer it works fine.

So, C-code works fine, but when you call C-compiler you get
Segmentation fault and symbolic screen is terminated.

I guess you
a) put MSSM_10.14 in CalcHEP directory
b) call make
c) use IMPORT MODEL menu option.

May be path to CalcHEP is very long on your computer?

Suppose you launch calchep in CalcHEP/work directory.
Then you can try to call it under debbuger gdb

gdb ../bin/s_calchep
r
     and after Segmentation fault call
bt
      send me what you see on the screen after 'bt' which should to
write sequence of commands which leads to crush.
      To quit debbuger call
q

Dear Alexander,

Indeed, the old problem disappear after I make the path to Calchep shorter.
However, I got another problem when call C-compiler or make&launch n_calchep. When I call c-compiler or make&launch n_calchep in Standard model, I got a new GUI window and everything works fine. But, when I try to do this for MSSM, there is no new window coming out and I got a massage: n_calchep is not generated. And the terminal give me following massage:

bash-3.2$ ./calchep
ar: creating archive proclib_0.a
ld: warning: ignoring file /Users/qingyunwang/Desktop/research/calchep/MSSM/lib/aLib.a, file was built for archive which is not the architecture being linked (x86_64): /Users/qingyunwang/Desktop/research/calchep/MSSM/lib/aLib.a

I installed MSSM by
a) put MSSM_10.14 in CalcHEP directory
b) call make
c) use IMPORT MODEL menu option.

However I noticed that, when I was calling make, I got following massage

bash-3.2$ make

So I think the problem may came from this so called aLib.a file, although I do not know how to fix it. Could you please help me to fix this problem?

 I really very appreciate your help.

Dear Alexander,

Removing the aLib.a and then call "make" once more perfectly solved my problem! This looks just like a magic for me. Since the aLib.a which I just deleted appear again after I call "make" once more, but this time I am able launch c-compiler and it give me a new GUI window as expected.

I really appreciate your help.

best,
Qingyun

Thanks Alexander Pukhov, that solved my question.
