Hello,

When I run a command in the shell I get the following result with a
non-zero exit status:

-----%<-----
$ lblrtm

Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

Backtrace for this error:
#0 0x7F1874C5AB07
#1 0x7F1874C5B11E
#2 0x3000C3269F
#3 0x45C2E5 in eminit_
#4 0x473F4A in xmerge_
#5 0x408F96 in xlayer_
#6 0x429333 in MAIN__ at lblrtm.f90:0
Segmentation fault (core dumped)

$ echo $?
139
-----%<-----

When I run the same command in my IDL script via spawn, I see the following:

-----%<-----
IDL> SPAWN, 'lblrtm', stdout, stderr, EXIT_STATUS = exit_stat
IDL> foreach s, stderr do print, s

Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

Backtrace for this error:
#0 0x7F75D828DB07
#1 0x7F75D828E11E
#2 0x3000C3269F
#3 0x45C2E5 in eminit_
#4 0x473F4A in xmerge_
#5 0x408F96 in xlayer_
#6 0x429333 in MAIN__ at lblrtm.f90:0

IDL> print, exit_stat
0
-----%<-----

Umm...anyone know why my IDL EXIT_STATUS (0) is different from my shell
exit status (139)?

Do I need an extra switch in the SPAWN command or...?

Thanks for any info.

cheers,

paulv
