Subject: Next runtime messages to be ommitted if compiled with clang using flag '-fsanitize'.
X-Git-Tag: 2.4-beta2~914
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=f8f86a1a8172fa8b66ffaf7e04c0b723ee2b4866;p=lyx.git

Next runtime messages to be ommitted if compiled with clang using flag '-fsanitize'.

Prevent the return of impossible values for 'enum flags'.
For instance the result of '~Update::Force' at src/BufferView.cpp:3025 without this patch
is '4294967293'.
