hi,
i'm trying to debug an ugly application with ElectricFence. in fact, on x86-64 box with 8GB ram and 16GB swap i'm getting following error:
"ElectricFence Exiting: mprotect() failed: Cannot allocate memory"
the program has been compiled with gcc-4.5, glibc-2.11.1, kernel-2.6.32. did you ever come across such (kernel/glibc) limitations?
here's a simple testcase which triggs -ENOMEM in mprotect().
#define N 100 #include<stdlib.h>
double **bm; int main(){ int i; long NN = 4*N*N; int kmax=100;
bm = (double **)malloc((time_t)NN*sizeof(double *)); for(i=0; i<NN; ++i){ bm[i] = (double*)malloc((time_t)kmax*sizeof(double)); }
for(i=0; i<NN; ++i){ free(bm[i]); } free(bm); return 0; }
thanks for any hint,
BR, Pawel.
