Description Sergey 2016-05-11 11:14:17 UTC

When I tried to verify whether bug 362934 was fixed in upstream, I integrated SVN trunk valgrind as of 11.05.2016 into AsusWRT-Merlin 380.58. Again the only change is in configure script: armv7*) -> arm*).

Now valgrind fails with assertion:

Comment 1 Julian Seward 2016-07-05 07:25:19 UTC

valgrind: m_transtab.c:2459 (vgPlain_init_tt_tc): Assertion 'sizeof(TTEntryC) <= 88' failed
was a temporary problem; I am sure it has now been fixed.

Comment 2 Sergey 2016-07-05 11:19:30 UTC

Just tried the latest r15901 on a slightly different platform (ASUS RT-AC87U) and with different executable.
Result is the same:

admin@RT-AC87U-0C18:/tmp/home/root# valgrind ssh

Segmentation fault

Comment 3 wangyiduo999 2016-07-11 19:20:30 UTC

I also have the same problem with my arm device

/usr/sbin # valgrind ls -l
==24846== Memcheck, a memory error detector

Comment 4 Julian Seward 2016-07-21 12:46:50 UTC

Err, sorry for the stupid bug.  That value needs to be 96 on arm-linux, not 88.

Comment 5 Julian Seward 2016-07-21 12:48:13 UTC

Fixed, r15912.
