            Bug ID: 15810
           Summary: gdb 7.3.1/7.5 unlink files
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: normal
          Priority: P2
         Component: corefiles
          Assignee: unassigned at sourceware dot org
          Reporter: kdevel at vogtner dot de

./configure --prefix=/tmp/loc2
make
make install
strace -fFeunlink /tmp/loc2/bin/gdb

Output:

unlink("/tmp/loc2/share/gdb/python/gdb/command/__init__.pyc") = 0
unlink("/tmp/loc2/share/gdb/python/gdb/command/explore.pyc") = 0
unlink("/tmp/loc2/share/gdb/python/gdb/command/prompt.pyc") = 0
unlink("/tmp/loc2/share/gdb/python/gdb/prompt.pyc") = 0
unlink("/tmp/loc2/share/gdb/python/gdb/command/pretty_printers.pyc") = 0

Starting or running gdb shall never unlink files in the fs subtree where
software is installed. gdb at least of version 7.3.1 performs some additional
unlinks in the part of the filesystem where the compiler is installed when the
"run" command is issued:

unlink </.../gcc-4.6.4/lib64/../share/gcc-4.6.4/python/libstdcxx/__init__.pyc>
unlink
</.../gcc-4.6.4/lib64/../share/gcc-4.6.4/python/libstdcxx/v6/__init__.pyc>
unlink
</.../gcc-4.6.4/lib64/../share/gcc-4.6.4/python/libstdcxx/v6/printers.pyc>

which cannot be straced but be intercepted with a preloaded shared object.

All this can be circumvented by using "--with-python=no" as configuration
parameter.
