https://build.opensuse.org/request/show/1152216
by user pluskalm + anag+factory
- Update to 4.9.1:
* Improved detection of bad remote storage URLs gracefully. This also fixes
crashes seen in ccache’s own test suite.
* Made caching completely disabled when modification of a source or include
file is detected during ccache invocation. Previously this was only done for the direct mode.
* Fixed an MSVC crash when using /Zi with many concurrent compilations.
* Fixed a crash when -arch is the last compiler option.
- Drop no longer needed fix2038.patch
