soooo....

I checked the coredump and found this:

1) its not acroread what coredumps but bash binary (the binary used for the
script)
when I manually tried running the bash and "exec /bin/ls" etc. it worked
I havent investigated further waht causes the coredump

2) I put printf() at the very begining of the linux_semctl() function and
ran the acroread binary. The printf was not printed (ie. it didnt used the
linxu_semctl function)

3) here is a outpuit od -DDEBUG compiled linuxolator and running of acroread
(the first 3 lines are output of command line, it might be interesting to see
the VA = 0x0)
