Bug#906152: libopenblas-base: version 0.3.2+ds-1 makes gimp hang indefinitely

[Rogério Brito]

Package: libopenblas-base
Version: 0.3.2+ds-1
Severity: serious
Justification: breaks unrelated software

Hi.

First of all, I selected serious instead of the more appropriate critical
severity because I don't want to severity inflation.

On the other hand, if you think that this is a severity too high, feel free
to set it to a more appropriate level (as long as we get everything fixed).

OK, now, to the actual report. With version 0.3.2 of openblas installed,
whenever I call gimp (I always start programs from the command line), it
just sits there and doesn't even show its splash screen.

If I interrupt the execution with Ctrl+C, then I get a "Segmentation fault"
message, which would lead me to think that the program would not even have
finished being linked to all the shared libraries that it needs.

If I run gimp under strace, I see that it hangs in a mutex call that never
proceeds.

I searched the web and I found the following discussion:
<https://bbs.archlinux.org/viewtopic.php?id=238684>.

In it, it is suggested that the problem might have be with openblas and,
indeed, I removed libopenblas-base and voilá: with just atlas and the
reference blas installed, gimp fires up as expected on this machine.

This computer is, BTW, a notebook with a Core 2 Duo processor and, when I
start gimp now, I get the following message (that I used to get with
openblas before the upgrade to 0.3):

,----

If any further information is needed, please let me know.


Thanks,

Rogério Brito.
