bug#12544: -r110296..110297 causes random crashes in optimized build on Windows

[Fabrice Popineau]

I don't know if it is related or not, but I get a few crashes too when doing a bootstrap and

while compiling some .el files. An example of a backtrace is :

And the crash occurs after a

EnterCriticalSection(crit)

instruction.

I have the same behaviour with both 32bits and 64bits exe.
