Yes, the problem is in the new function "loadSymFile"
I don't know if this is supported in a more recent version of visual C
than the one used in cirrus-ci,
I am always very cautions about variable length arrays, anyway. Like any
local variable, they are allocated on the stack; but with a VLA one can
only cross one's fingers to hope that it fits without causing a stack
exhaustion.
See
https://wiki.sei.cmu.edu/confluence/display/c/ARR32-C.+Ensure+size+arguments+for+variable+length+arrays+are+in+a+valid+range
... which incidentally also happens to mention: "Variable length arrays
are not supported by Microsoft compilers." This is confirmed by
https://learn.microsoft.com/en-us/cpp/build/reference/std-specify-language-standard-version?view=msvc-170:
"Variable length array (VLA) support isn't planned. VLAs provide attack
vectors [...]".
