I can't duplicate it with a shell script, but I made some progress in
locating the problem; I found that I had both a gdb and a gdb.exe in
/usr/lib; these two seems to "cancel" each other and the gdb.exe from the
end of the PATH is called instead. Here is some test code reproducing the
problem:
hello.c:
#include <stdio.h>
#ifndef NUMBER
#define NUMBER 0
#endif
int main()
{
printf("Hello number %d\n", NUMBER);
return 0;
}
gcc hello.c -DNUMBER=1 -o /usr/bin/hello
gcc hello.c -DNUMBER=2 -o /tmp/hello
PATH=/usr/bin:/tmp
hello
Hello number 1
So far, so good. Now here is the trick:
cd /usr/bin
cp hello.exe hello
PATH=/usr/bin:/tmp
hello
Hello number 2
Gotcha. hello and hello.exe from /usr/bin are both ignored in favor of
hello.exe in /tmp, despites the PATH order.
