Dear GLPK Team,
I have an mip problem (see attachment) that can be solved in under a
second with glpk 4.58 but loops with glpk 4.64. That is, the gap does
not go
Hello Andrew,
when compiling GLPK-4.64 with GCC 7.2 the following warning is shown:
misc/wclique1.c: In function '_glp_wclique1':
misc/wclique1.c:121:7: warning: 'memset': specified size between
18446744071562067968 and 18446744073709551615 exceeds maximum object

Please, add the missing explicit conversions to silence the warning.
Distributions like Debian want to be able to set a compiler flag which treats every warning as error.

It is a bad idea. Besides, the GNU Coding Standard recommends not to do
explicit casting if it is not needed.
