>From comment #12 (from Fernando):
"""
Per this part of the stacktrace:
/usr/sbin/mysqld(_ZN11TC_LOG_MMAP4openEPKc+0x6f4)[0x384ffd54]
/usr/sbin/mysqld(_ZN11TC_LOG_MMAP4openEPKc+0x2cc)[0x384ff92c]
And sorry if this is a stupid question, but do you think it might be related to
the pagesize?
"""
In x64 object file, 0x6f4 == 1780 which gives us:
file_length= opt_tc_log_size;
0x00000000004c2fd3 <+1763>: lea 0x891f36(%rip),%rax # 0xd54f10
<opt_tc_log_size>
*** 0x00000000004c2fe4 <+1780>: mov (%rax),%r14
0x00000000004c2fee <+1790>: mov %r14,0x210(%rbx)
if (mysql_file_chsize(fd, file_length, 0, MYF(MY_WME)))
0x00000000004c305a <+1898>: test %r13d,%r13d
0x00000000004c305d <+1901>: jne 0x4c2ef6 <TC_LOG_MMAP::open(char
const*)+1542>
0x00000000004c3063 <+1907>: mov 0x210(%rbx),%rsi
When the key_file_tclog can't be opened. Right after, we have:
npages=(uint)file_length/tc_log_page_size;
DBUG_ASSERT(npages >= 3); // to guarantee non-empty pool
Which upstream fix pointed by Trent talks about.
And according to:
#define TC_LOG_PAGE_SIZE 8192
#define TC_LOG_MIN_SIZE (3*TC_LOG_PAGE_SIZE)
ulong opt_tc_log_size= TC_LOG_MIN_SIZE;
And based feedback, we should skip the ASSERTs for bigger page-sizes,
definitely.

Looks good to me.
