claws-mail: runtime crash: malloc error

[jurgen.defurne@…]

After upgrading to Mountain Lion and updating ports, the only problem I still have is that claws-mail has become unstable due to a malloc problem:

claws-mail(3106) malloc: *** error for object 0x7ff5450216e8: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
claws-mail(3106) malloc: *** error for object 0x7ff5450216e8: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug

Maybe this is an upstream problem?

[jurgen.defurne@…]

It does not crash immediately, I can still download mail and read things, so it is not that urgent. However, I use claws-mail already since the time it was called sylpheed, and it is the first time in all those years that I have problem with it.

[ryandesign (Ryan Carsten Schmidt)]

Can you provide a reproduction recipe—a set of steps that we could follow to see the crash for ourselves?

It might be a problem with having used the clang compiler. You could try uninstalling claws-mail and reinstalling it with a different compiler.

[jurgen.defurne@…]

It seems to crash after it has fetched mail and sorts it into the different folders, so not due to any action of me. Just set it up to automatically fetch mail and leave it be.

I will try the suggestion, thanks.

[jurgen.defurne@…]

It seems more stable with llvm-gcc-4.2, although the issue is still there. Trying to build with apple-gcc42 returns

Error: org.macports.configure for port claws-mail returned: Invalid value for configure.compiler

[jurgen.defurne@…]

More information, by running claws-mail from a console.

The following is reported by claws-mail, but apparently does not immediately cause a crash:

decraemerDataNews++ STATS ++ INC 5 5
claws-mail(10885) malloc: *** error for object 0x7fb3bb023600: double free
*** set a breakpoint in malloc_error_break to debug
++ STATS ++ INC 5 0
++ STATS ++ INC 5 0

[jurgen.defurne@…]

In the same session as the previous information:

claws-mail(11671) malloc: *** error for object 0x7fb3bbe43008: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
++ STATS ++ INC 6 0

[jurgen.defurne@…]

Today's crash:

++ STATS ++ INC 102 1
claws-mail(4651) malloc: *** error for object 0x7ff4aa087b80: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

[ryandesign (Ryan Carsten Schmidt)]

Is this still a problem with 3.9.2?

[pmetzger (Perry E. Metzger)]

I cannot reproduce such issues, and it is from a quite old version of claws. I think closing the ticket for now would be best, unless someone can give a recipe for reproducing the problem.
