Re^2: segmentation fault for perl by Anonymous Monk on Jul 06, 2009 at 06:47 UTC
I am invoking the script x.pl from y.pl as system(x.pl); my $exit_status = $? >> 8; I am capturing the status always. It sometimes happen that x.pl is able to execute successfuly (it updates a database before exiting). But capturing the error status in y.pl shows the system(x.pl) has a exit status of segmentation fault. My os is solaris 10	[reply]

I am invoking the script x.pl from y.pl as system(x.pl); I take it to mean `system('x.pl');`. And I guess you made sure that x.pl has a correct #! line? `my $exit_status = $? >> 8;` I am capturing the status always. How do you know that your program died by segmentation fault? `$? >> 8` is whatever x.pl passes to its `exit` call, so from this value alone, you can not deduce that your program segfaulted. But if it does, it could be that either the Perl used has a problem (that's why I'm asking you about the #! line), or (more likely) that x.pl uses some Perl module which contains compiled parts, so this would be the place to look. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]
