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:
helge@remaxp:~/prog/db/rechnung$ export LD_PRELOAD=/usr/lib/debug/libc-2.3.2.so
helge@remaxp:~/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 0000000000000008 rip 00002aaaaac294a3 rsp 00007fffffffdac0 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:
