Package: valgrind
Version: 1:3.5.0-1
Severity: normal
I updated valgrind this weekend.
valgrind (1%3a3.5.0-1) at least partially ignores --demangle=no option.
The following false positive (I think) from libc prints like this in valgrind
1%3a3.4.1-1 with --demangle=no:
==24358== Invalid free() / delete / delete[]
==24358== at 0x4C2261F: _vgrZU_libcZdsoZa_free (vg_replace_malloc.c:323)
==24358== by 0x514ADEA: (within /lib/libc-2.9.so)
==24358== by 0x514A981: (within /lib/libc-2.9.so)
==24358== by 0x4A1E560: _vgnU_freeres (vg_preloaded.c:60)
==24358== by 0x507E4B4: exit (in /lib/libc-2.9.so)
==24358== by 0x50665CC: __libc_start_main (in /lib/libc-2.9.so)
==24358== Address 0x4039178 is not stack'd, malloc'd or (recently) free'd
==24358==
==24358== ---- Print suppression ? --- [Return/N/n/Y/y/C/c] ---- y
{
<insert a suppression name here>
Memcheck:Free
fun:_vgrZU_libcZdsoZa_free
obj:/lib/libc-2.9.so
obj:/lib/libc-2.9.so
fun:_vgnU_freeres
fun:exit
fun:__libc_start_main
}
But with 1%3a3.5.0-1 it looks like this:
==24071== Invalid free() / delete / delete[]
==24071== at 0x4C21DBC: free (vg_replace_malloc.c:325)
==24071== by 0x5149DEA: ??? (in /lib/libc-2.9.so)
==24071== by 0x5149981: ??? (in /lib/libc-2.9.so)
==24071== by 0x4A1E590: _vgnU_freeres (vg_preloaded.c:62)
==24071== by 0x507D4B4: exit (in /lib/libc-2.9.so)
==24071== by 0x50655CC: (below main) (in /lib/libc-2.9.so)
==24071== Address 0x4038cd0 is not stack'd, malloc'd or (recently) free'd
==24071==
==24071==
==24071== ---- Print suppression ? --- [Return/N/n/Y/y/C/c] ---- y
{
<insert_a_suppression_name_here>
Memcheck:Free
fun:free
obj:/lib/libc-2.9.so
obj:/lib/libc-2.9.so
fun:_vgnU_freeres
fun:exit
fun:(below main)
}
This also leads to difficulties with suppression files, since the
manual recommends that suppressions should be generated and written
with --demangle=no.
