[Bug]: valgrind bad system call #17359

Closed babaric-dev closed 6 months ago

babaric-dev commented 1 year ago

Problem description

Self explanatory.

What steps will reproduce the bug?

Install valgrind and run any program:

valgrind --tool=massif ls

Even valgrind itself breaks:

valgrind --tool=massif valgrind

Bad system call

Note this does not happen when running valgrind --help

What is the expected behavior?

Programs run as expected without valgrind (no bad syscall). But this should also be the case when invoking via valgrind

xtkoba commented 1 year ago

I cannot confirm this because I do not have access to any x86_64 Android environment.

Sharing strace output of the command may help.

babaric-dev commented 1 year ago

Sorry, but I'm not sure if I want to share the output of strace here.

2096779623 commented 1 year ago

I cannot reproduce it on my aarch64 device.

truboxl commented 1 year ago

Is this on Windows 11?

babaric-dev commented 1 year ago

Yes. Windows 11, unsupported region, vanilla MSIXBundle without any patches, downloaded from Adguard Store, Amazon Appstore removed with adb command.

xtkoba commented 1 year ago

Not sure if this is specific to WSA or reproducible with other environments such as AVD.

babaric-dev commented 1 year ago

Does anyone have an AVD or a Windows Arm machine to test WSA Termux Valgrind on Arm? Please test and report the results thanks.

zavocc commented 1 year ago

WSA can transparently run arm/arm64 binaries /libraries/apps on x86_64 using libhoudini, so installing https://github.com/termux/termux-app/releases/download/v0.118.0/termux-app_v0.118.0+github-debug_arm64-v8a.apk would simply let you use arm64 Termux on Windows Subsystem for Android, this requires however uninstallation of existing Termux app.

The more I try look deeper the issue, the more I am convinced upstream never advertise valgrind support for AMD64/Android https://valgrind.org/docs/manual/dist.news.html https://bugs.kde.org/show_bug.cgi?id=379764 https://bugs.kde.org/show_bug.cgi?id=379878 https://bugs.kde.org/show_bug.cgi?id=368529

Its also questionable if valgrind on Android ever work. List of bugs at upstream
