Package: tetex-bin
Version: 3.0-17
Severity: normal
A few moments ago I found "texshow" in the help section of my window
manager and wanted to try it out, which did not produce any screen
output (i.e. no window appeared). Subsequent search turned out, that
the menu entry calls
/usr/bin/texshow
Running it from an xterm seemed to work at first. But sometimes it
crashes also:
helge@remaxp:~$ /usr/bin/texshow

/usr/bin/texshow: line 22: 25369 Abgebrochen perl "$p" ${1+"$@"}
(Abgebrochen == Aborted)
I tried to figure out a pattern when it starts and when it does not,
but failed. The point of the memory corruption varies from call to
call, btw.:
*** glibc detected *** malloc(): memory corruption: 0x0000000000f7cfa0 ***
*** glibc detected *** malloc(): memory corruption: 0x0000000000f7fb90 ***
*** glibc detected *** malloc(): memory corruption: 0x0000000000f77ba0 ***
(but not the line number, i.e. 22).
I figured out, what was actually called (I use bash as sh):
perl /usr/share/texmf-tetex/scripts/context/perl/texshow.pl
Unfortunately, now I don't get a line number:
helge@remaxp:~$ perl /usr/share/texmf-tetex/scripts/context/perl/texshow.pl

It dies in
show_command ($command);
When I add the line
print "After setup $command\n";
before this line in texshow.pl it seems to work properly always.
But $command is empty, i.e. this line prints:
After setup
Please tell me what else to try to narrow this down.
Could this be related to me using grsec?
