Bug ID: 26170
Summary: gdb.base/testenv.exp loops on Linux/sparc64
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: tdep
Assignee: unassigned at sourceware dot org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Host: sparc64-unknown-linux-gnu
Target: sparc64-unknown-linux-gnu
Build: sparc64-unknown-linux-gnu
While testing current master on Linux/sparc64, the gdb.base/testenv.exp would
loop:
PASS: gdb.base/testenv.exp: test_inherit_env_var: test1: test passing
TEST_GDB_G
LOBAL to GDB
FAIL: gdb.base/testenv.exp: test_inherit_env_var: test1: TEST_GDB_GLOBAL, get
nu
m vars
FAIL: gdb.base/testenv.exp: test_inherit_env_var: test1: TEST_GDB_GLOBAL,

med
FAIL: gdb.base/testenv.exp: test_inherit_env_var: test1: printf "var: %s\n",
env
p[0] ? envp[0] : ""
[...]
FAIL: gdb.base/testenv.exp: test_inherit_env_var: test1: printf "var: %s\n",
envp[4443985] ? envp[4443985] : ""
which I only noticed after those 4.4+ million iterations.
The failure mode is like this:
(gdb) run
Starting program:

--- Comment #1 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> ---
Thanks for catching this. This would explain why the gdb testsuite with version
10 never finishes.
I guess we should disable this particular test for the time being.
