Package: libc6
Version: 2.3.2.ds1-22
Severity: normal
I am writing a small perl programm (see attached). If I run this
programm under Sarge/amd64, it segfaults. To reproduce:
[EMAIL PROTECTED]:~/prog/db/rechnung$ export
LD_PRELOAD=/usr/lib/debug/libc-2.3.2.so
[EMAIL PROTECTED]:~/prog/db/rechnung$ env LANG=C ./rechnung.pl
n, Geschäft: HP
Geschäftsname:: (HP)
Währung:: (Euro)
Währung:: (Euro) Dollar
:
n, Produkttyp (Foodrechnung.pl[26712]: segfault at 0008 rip
2ac294a3 rsp 7fffdac0 error 4
Speicherzugriffsfehler (core dumped)
i.e., press HP enter enter Dollar enter
If I run the very same program with current sid (but in an ia32 changeroot,
not amd64) the programm does not segfault. Looking at the corefile
with gdb, I see:

(gdb) quit
I tried replacing /usr/bin/perl by /usr/bin/debugperl and then the
segfault is gone.
I guess it's time to move this machine to testing?
If you want, I can try this on current testing/ppc (but also 32bit).
Btw. other input sequences crash the programm as well ...
Please reassign to perl oder readline or ??? if glibc is the wrong
package to report this against.
