-----------------------------+--------------------------
In between hrev54154 (14th Sep 2020) and hrev54662 (21st Oct 2020), a
regression was introduced which fails a c++ new (malloc) when requesting
more than 2Gb of memory (x64 architecture, with 32Gb available memory).
Stack trace:
_kern_debugger +0x7
abort + 0x4a
llvm::report_bad_alloc_error(char const*, bool) + 0xea
operator new(std::size-t) + 0x3a
The file belongs to /sources/gcc-8.3.0/libstdc++-v3/libsupc++/new_op.cc
Requested buffer size was 2,053,316,608 bytes.
This has been working for a number of years until the regression was
introduced between hrev54154 (last known working version) and hrev54662
(earliest detected error). Validated on 3 boxes (MacBookPro, Ryzen2700,
Ryzen3700) with multiple haiku images (disk/usb/ssd/nvme).
