gitian vs self-compiled on ARM 32-bit gettxoutsetinfo #18538
Description
UPDATE: see #18538 (comment)
Having the low-end system ODROID-HC1.
The downloaded binaries 0.19.1 behave as expected:
$ time bitcoin-cli -rpcclienttimeout=3600 gettxoutsetinfo
{
"height": 624598,
"bestblock": "0000000000000000001366754ef0fb1b483f1d7d64e3f561c262fdf5978ffbc0",
"transactions": 39618423,
"txouts": 66517746,
"bogosize": 4997008193,
"hash_serialized_2": "53f16a7e24542b3079eb7246660126392107fe87b2233ec27070386d333de708",
"disk_size": 4009464235,
"total_amount": 18307304.82089071
}
real 6m33.513s
user 0m0.004s
sys 0m0.023s
Monitoring the b-httpworker.0 thread via htop shows that it is running almost all the time.
The similar results I've received from other downloaded versions: 0.19.0.1 and 0.18.0.
The built locally binaries (with and without depends) show very different results:
$ time bitcoin-cli -rpcclienttimeout=3600 gettxoutsetinfo
{
"height": 624679,
"bestblock": "000000000000000000117e2b43965e568b5d50004f347f8b6ee642191c2895a8",

}
real 56m23.878s

sys 0m0.030s
Monitoring the b-httpworker.0 thread via htop shows that it is blocked very often.
This difference in behavior is so strange, I'm not sure how to debug it...
The compiler on machine:
$ g++ --version | head -1
g++ (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) 7.5.0
Please note that this issue differs from #16979.
