When trying to push the patch for Bug#33479, it now crashes the server:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x6c730124
0x00392662 in Dbb::updateSequence (this=0x6c730000, sequenceId=1853453114, delta=0, transId=0) at Dbb.cpp:850
850		if (!sequenceSection)

I will push the patch and the test and also disable the test (into mysql-6.0-bugteam)

How to repeat:
enable parts/partition_auto_increment_falcon.test and run it.

Suggested fix:
fix the bug in the falcon code :)

Thank you for the report.

I can not repeat described behavior. Which OS do you use and how you compile server?

I can repeat it on my MacBook (Late 2007, Mac OS X 10.5.2):
bk clone -r'mattiasj@witty.|ChangeSet|20080509053829|49449' mattiasj@bk-internal.mysql.com:/home/bk/mysql-6.0-bugteam 60-bugteam-mj_push
cd 60-bugteam-mj_push
cd mysql-test
export MTR_MEM=1; export MTR_BUILD_THREAD=2
# I forgot to enable the test first...
./mtr --suite=parts partition_auto_increment_falcon
(enable partition_auto_increment_falcon in suite/parts/t/disabled.def)
./mtr --suite=parts partition_auto_increment_falcon

Has the bug too)

I have successfully repeated the bug, but I have also at least once, with the latest mysql-6.0-bugteam, manage to do a new clone, compiled with compile-pentium-debug-max and succeeded with the test!

Thank you for the feedback.

Verified as described.

When I run it in mysql-6.0-bugteam or in mysql-6.0 (main) this crash does not occur anymore!

Kevin, can you verify this?

      Bug#36595 no longer fails
[3 Sep 2008 21:06] Kevin Lewis
I made the test case active again, since it seems to work now for both me and Mattias.
