That dll is huge (181Mb not counting dependencies), so I tried to strip it but
after that Firefox could run without problems.

I tried to load that dll form a simple testcase doing just a LoadLibrary, but
then it loads fine.

Then I tried to run strace on both Firefox and the testcase in order to
compare, and apparently the issue is that the mmap2() call fails when running
from Firefox, but not from the testcase.
> From the testcase:

mmap2(0x6c140000, 176517120, PROT_READ|PROT_WRITE|PROT_EXEC,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x6c140000
> From Firefox:

mmap2(0x6c140000, 176517120, PROT_READ|PROT_WRITE|PROT_EXEC,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)

I'm wondering why the mmap2() call fails when Firefox tries to load that .dll.
I've got enough memory, and ulimit -a doesn't show maximum memory size
limitation.

I could put an archive of the build somewhere if you want to try, but it's
rather large (600Mb uncompressed).
