Package: libpgplot-perl
Version: 1:2.20-1
Severity: normal
Hi,
I build the libpgplot-perl package on Lenny. It works fine on i386,
but segfaults on amd64 with the following little test script:
---snip---
#!/usr/bin/perl
use PGPLOT;
$|=1;
pgbegin(0,"pgplot.gif/gif",1,1);
print "Debug: A\n";
pglabel("foo, z",'bar Mpc','Some Distances');
print "Debug: B\n";
pgend;
---snap---
Example Lenny amd64:
!534 Z42 ?139 L1 a...@zwoelfi:pts/7 (-zsh) 22:00:59 [~/tmp] > ./pgplot.pl
Debug: A
%PGPLOT, Writing new GIF image as: pgplot.gif_32566
[1] 10689 segmentation fault (core dumped) ./pgplot.pl
!534 Z43 ?139 L1 a...@zwoelfi:pts/7 (-zsh) 22:10:45 [~/tmp] >
Backtrace:
Program received signal SIGSEGV, Segmentation fault.

Example Lenny i386:
!531 Z19 ?0 L1 a...@kneazle:pts/25 (-zsh) 22:03:35 [~/tmp] > ./pgplot.pl
Debug: A
Debug: B
!532 Z20 ?0 L1 a...@kneazle:pts/25 (-zsh) 22:11:09 [~/tmp] >
I haven't tested if it works on Sid i386, but at least on Sid amd64
(with pgplot5 5.2.2-15), it segfaults, too:
!814 Z326 ?1 L1 a...@kiva6:pts/10 (-zsh) 22:09:49 [~/tmp] > ./pgplot.pl
Debug: A
%PGPLOT, Writing new GIF image as: pgplot.gif_32601
Debug: B
[6] 23752 segmentation fault (core dumped) ./pgplot.pl
!815 Z327 ?139 L1 a...@kiva6:pts/10 (-zsh) 22:11:32 [~/tmp] >
Interestingly "Debug: B" gets printed on Sid, but not on Lenny amd64.

Feel free to reassign it to the pgplot5 package if you suspect the bug
in there.
