Compilers that do not support the C11 standard, or do not implement gcc extensions, may not support variable length arrays.
VLAs are a C99 thing.
The code prior to this commit produced the following warning when compiled with "-Wvla -std=c90". warning: ISO C90 forbids variable length array ‘array’ [-Wvla] This commit removes the variable length array from the PMD debug trace function by allocating memory dynamically on the stack using alloca().
Is alloca() even included in *any* C standard? As far as I see, it just achieves the same thing in an uglier, less portable way than VLAs.
