Bug

Target
LPC1768 (and possibly LPC11U24)

Toolchain:
ARM (online IDE)

Toolchain version:
5.06

meed-os sha:
f4864dc

Expected behavior
LocalFileSystem API should work.

Actual behavior
LocalFileSystem API does not seem to work with mbed_lib_rev138.
If I rollback to mbed_lib_rev137, it works fine.

Steps to reproduce
Create new problem as code below with mbed_lib_rev138.

#include "mbed.h"

#if !defined(TARGET_LPC1768) && !defined(TARGET_LPC11U24)
#error This target does not support LocalFileSystem.
#endif

LocalFileSystem local("local");               // Create the local filesystem under the name "local"
 
int main() {
    FILE *fp = fopen("/local/out.txt", "w");  // Open "out.txt" on the local file system for writing
    fprintf(fp, "Hello World!");
    fclose(fp);
}

@toyowata Any pointers ? I checked the history, local filesystem and lpc176x have not been changed for some time.

@0xc0170 Not sure the trigger of this problem, but I got one warning message with mbed_lib_rev138 build which was not produced by previous library.

Warning: Function "mbed::FileSystemLike::FileSystemLike(const char *)" (declared at <a href="#" onmousedown="mbed_doc_goto('/LocalFileSystem_HelloWorld//extras/mbed_093f2bd7b9eb/drivers/FileSystemLike.h', '47'); return false;">/extras/mbed_093f2bd7b9eb/drivers/FileSystemLike.h:47</a>) was declared "deprecated" in "extras/mbed_093f2bd7b9eb/drivers/LocalFileSystem.h", Line: 99, Col: 53

@0xc0170 I saw that the FileLike class (inherited by LocalFileSystem via FileSystemLike) had been modified between rev137 and rev138. It does not use FileHandle instance any more, but not sure this is a cause of this problem.
