Bug ID: 21220
Summary: "restore" for large data structures extremely slow on
GNU/Linux
Product: gdb
Version: HEAD
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: arnez at linux dot vnet.ibm.com
Target Milestone: ---
On GNU/Linux, restoring a large array does not complete in reasonable time:
(gdb) p sizeof bigarray
$1 = 16777216
(gdb) dump bin mem foo.bin &bigarray &bigarray[sizeof bigarray]
(gdb) restore foo.bin binary &bigarray
Restoring binary file foo.bin into memory (0x10002060 to 0x11002060)
This operation appears to hang.
