Description Remi Collet 2013-10-09 12:33:59 EDT
Created attachment 810043 [details]

Working on pecl/Judy extension and trying to understand issue in the test suite, I finally think this is a bug in Judy library.

Please try the minimal reproducer attached.

$ gcc -Wall -lJudy reproducer.c -o reproducer

$ ./reproducer 3
OK - bit successfully set at 1
OK - bit successfully set at 2
2 bits set in Judy1 array
2 Indexes used 24 bytes of memory
OK - first bit set is at 1

$ ./reproducer 3
OK - bit successfully set at 269
OK - bit successfully set at 270
Erreur de segmentation (core dumped)

P.S. I have another issue with the iterator (JSLN) I will try to provide another reproducer.

Have you reported this upstream? That would seem to be the best place to me.

No, but as last version is from 2009... I'm a bit afraid...
Will try to investigate a little first.

P.S. and forget the JSLN, it works perfectly.

NB: this is a 64bits only bug. i386 is not affected.
Comment 4 Remi Collet 2013-10-10 13:16:03 EDT
@Paul, after some investigation, this is a gcc issue at the time this package (Judy-1.0.5-6.fc19) was build.

No issue with all tested build (fc14 to fc20, el5 and el6).

A simple rebuild with current gcc version in F19 solves this issue.

Can you please take care of this (I can do it if you prefer).
