Program with large BSS.
VERSION
Valgrind-3.16.0.GIT
SUMMARY
I get this error message:
valgrind: mmap(0x602000, 2147483648) failed in UME with error 22 (Invalid
argument).
valgrind: this can be caused by executables with very large text, data or bss
segments.
Valgrind could indicate a solution to this problem by suggesting the following
linker option:
-Wl,-Ttext-segment=0x68000000
STEPS TO REPRODUCE
1. gcc -o large large.c
2. valgrind ./large
3. gcc -Wl,-Ttext-segment=0x68000000 -o large large.c
4. valgrind ./large
OBSERVED RESULT
valgrind: mmap(0x602000, 2147483648) failed in UME with error 22 (Invalid
argument).
valgrind: this can be caused by executables with very large text, data or bss
segments.
EXPECTED RESULT
A message suggesting usage of the above mentioned linker option.
