Bug ID: 406422
Summary: none/tests/amd64-linux/map_32bits.vgtest fails too
easily
Product: valgrind
Version: 3.15 SVN
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
On various systems none/tests/amd64-linux/map_32bits.vgtest fails with first
mmap: Cannot allocate memory.
The problem is that the --aspace-minaddr is too tight. Newer glibc seem to mmap
some memory and so even our first mmap with MMAP_32BIT will fail.
The solution is to make a bit more memory < 2GB available. If there is 16MB
available the test always seems to succeed without needing too many tries.
