faketime 0.9.10-2.1ubuntu1 is stuck in -proposed. |
faketime 0.9.10-2.1ubuntu1 is stuck in -proposed with build failures on armhf.
On armhf, the testsuite confusingly fails with a stack smash error. But this error happens in bash, which isn't even meant to be the process under test.
Minimal reproducer:
# LD_PRELOAD=./src/libfaketime.so.1 bash -c 'exit 0'
*** stack smashing detected ***: terminated
Aborted (core dumped)
#
Confusingly, ltrace shows different results for the newly-built binary than from one built without 64-bit time_t.
# LD_PRELOAD=./src/libfaketime.so.1 ltrace --library '*faketime*' bash -c 'exit 0'
bash->getrandom(0x1f3bf08, 1, 0x9683b0, 0) = 0xc8202
bash->getrandom(0xc8203, 0xf7fad53c, 1023, 0xf7eef801) = 0xc8202
*** stack smashing detected ***: terminated
--- SIGABRT (Aborted) ---
+++ killed by SIGABRT +++
# LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/faketime/libfaketime.so.1 ltrace --library '*faketime*' bash -c 'exit 0'
bash->gettimeofday(0x8b07a0, 0) = 0
bash->getpid() = 819717
bash->gettimeofday(0xffb88714, 0) = 0
bash->getpid() = 819717
bash->gettimeofday(0xffb8871c, 0) = 0
bash->getpid() = 819717
+++ exited (status 0) +++
#
Unsetting -DFAKE_RANDOM in debian/rules does not fix the problem however.
So simply loading the LD_PRELOAD library without executing it seems to be enough to break bash. |
