Public bug reported:
Binary package hint: libpython2.7
While running apt-ftparchive with the following command on arm on
oneiric :
/usr/bin/apt-ftparchive packages . > Packages
it segvs. This is repeatable.
Via gdb I see the following:
tarting program: /usr/bin/apt-ftparchive packages . > Packages
Program received signal SIGSEGV, Segmentation fault.
0x4022ff92 in ?? ()
(gdb) bt
#0 0x4022ff92 in ?? ()
#1 0x400424be in ?? ()
#2 0x400424be in ?? ()
Dumping the address space for the process, I see we're in libpython2.7
