Statement is overflowing a buffer #8

Closed awissu closed 7 years ago

awissu commented 7 years ago

Hi! I bumped into rpmlint erros when building rpm in OBS:

[  251s] I: Statement is overflowing a buffer
[  251s] E: gcad3d bufferoverflow /usr/include/bits/string3.h:109

Build with flags: -O2 -g -m32 -march=i586 -mtune=i686 -fmessage-length=0 -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables

Hi, thanks for your effort; we could fix all warnings in the latest version but:

[ 251s] I: Statement is overflowing a buffer [ 251s] E: gcad3d bufferoverflow /usr/include/bits/string3.h:109

how did this happen - which statement was causing the overflow ? Can we reproduce this ? How do you "building rpm in OBS: " ? Franz

All serious bugs are fixed, thanks. After all tests in about a week the new version goes into the repository; then i will close this issue.
