Description Nikos Mavrogiannopoulos 2015-07-09 12:26:11 UTC
Description of problem:
Basic operation of bash reports a memory leak. While that is harmless per se, it generated several issues in a testsuite I run which detects memory leaks in the run programs.

$ valgrind --leak-check=full /bin/bash -c 'exit 0'

==16709== 12 bytes in 1 blocks are definitely lost in loss record 83 of 292
==16709==    at 0x4A06C10: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
==16709==    by 0x18928F: xmalloc (in /usr/bin/bash)
==16709==    by 0x18306A: set_default_locale (in /usr/bin/bash)
==16709==    by 0x1360B0: main (in /usr/bin/bash)


(note that the above is with debuginfo symbols installed, but for some reason they cannot be read).

Comment 1 Nikos Mavrogiannopoulos 2015-07-09 12:28:51 UTC
btw. The example above failed example is identical to what gnulib uses to determine a working valgrind. That is, if bash has a memory leak, gnulib will fail to detect valgrind.

Hi Nikos,
this is already fixed, built and in bodhi, waiting for more karma ;)

Comment 3 Nikos Mavrogiannopoulos 2015-07-10 07:53:28 UTC
That build doesn't resolve the issue for me.

$ rpm -q bash
bash-4.3.39-4.fc22.x86_64

$ valgrind --leak-check=full /bin/bash -c 'exit 0'
==3667== 12 bytes in 1 blocks are definitely lost in loss record 85 of 296
==3667==    at 0x4A06C10: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
==3667==    by 0x18928F: xmalloc (in /usr/bin/bash)
==3667==    by 0x18306A: set_default_locale (in /usr/bin/bash)
==3667==    by 0x1360B0: main (in /usr/bin/bash)
