Starting the end of last week, gcc has started behaving badly. Whether I invoke

in bash (or make dies with an "interrupted" error.
But I'm stumped.
Smells like a hardware problem to me - I'd suggest testing it thoroughly with
memtest86 or similar.
Also run it through `strace -f gcc -o hello.exe hello.c` a few times and see if
it's sticking in the same spot every time (which would indicate software)?
Never blame hardware until you have eliminated the likelihood of BLODA (Big List
Of Dodgy Apps <https://www.cygwin.com/acronyms/#BLODA>: FAQ 4.44. What
applications have been found to interfere with Cygwin?
<https://cygwin.com/faq/faq.html#faq.using.bloda>): poorly written employee
monitoring and control software, often marketed as "End Point Protection",
"Security", or AV products, which can not deal with, and must bypass interfering
with emulators, like Cygwin or Git for Windows MSYS2.
Export CYGWIN=detect_bloda (BLODA detection code
<https://cygwin.com/legacy-ml/cygwin/2012-02/msg00797.html>) and/or run gcc
under strace 'strace -o gcc.strace gcc -o hello hello.c' to see if there are any
non-Cygwin and non-Windows (may still be installed under /Windows/Systems32/)
DLLs loaded.
If you can, bypass products interfering with Cygwin programs under its
<CYGWIN_ROOT>, or <CYGWIN_ROOT>/*bin/..., <CYGWIN_ROOT>/lib/...,
<CYGWIN_ROOT>/libexec/... paths.
