In commit 9cc586e605e3db1 I changed the low-level key-file reading routines like read_header and read_body so that they read from a BinarySource via get_byte(), rather than from a FILE * via fgetc. But I forgot that the two functions don't signal end-of-file the same way, so testing the return value of get_byte() against EOF is pointless and will never match, and conversely, real EOF won't be spotted unless you also examine the error indicator in the BinarySource. As a result, a key file that ends without a trailing newline will cause a tight loop in one of those low-level read routines.
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
The PuTTY home web site is

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
