Check failed: GetProcessWidePtrComprCage()->IsReserved() (9.4.146.13, Debian 11)

[Thorsten]

Hi,

I'm using the following configuration:

$ cat args.gn 

is_debug = true

target_cpu = "x64"

use_goma = false

is_component_build = true

symbol_level = 1

under Debian 11 with Version 9.4.146.13.

Compilation was successful.

When running the unittests I get a crash (see callstack below). The same crash I also get under windows build with MSVC.

Is this something that should concern me?

Thanks!

Hi again,

any hints about "GetProcessWidePtrComprCage" would be helpful ...

[Jakob Kummerow]

Most people on the team (as well as our build bots) build x64.debug builds on Debian regularly, so the fact that you're seeing failures there is surprising. You may have to investigate a bit. Looks like line 115 in isolate-allocator.cc should have created the reservation that the CHECK in line 137 is complaining about.

Maybe something is special about your system configuration, possibly related to large (4GB) virtual memory reservations? But even if that was the case, V8's code should already be checking for any failures...

I've set "v8_enable_pointer_compression_shared_cage = false". The tests are working now.
