* Fixed an overflow issue in `bowtie-build` that would sometimes
yield corrupt "large" (64-bit) indexes; the resulting index
would sometimes cause `bowtie` to hang. Note: `bowtie2-build`
does not have this issue.
* Fixed an issue in `bowtie` causing XM:i SAM optional field to
sometimes be off by 1 when using the `-m/-M` flags.
* Fixed an issue that would sometimes cause deadlocks in `bowtie`
when running multithreaded.
* Fixed an issue causing build errors when compiling against
a pre-C++11 standard.
