Hi,
I have an executable whose start address(__executable__start) has been
modified using custom linker script. Valgrind bails out
with the following error.
PROVIDE (__executable_start = 0x00048000); . = 0x00048000 + SIZEOF_HEADERS;
>> linker script for modifying executable start.
valgrind: mmap(0x48000, 251879424) failed in UME with error 22 (Invalid
argument).
valgrind: this can be caused by executables with very large text, data or
bss segments.
Below is the program header details of the executable.
Program Headers:

Is it possible to edit configure.in script so that valgrind's memory
mapping doesn't collide with that of my executable ?
