That claim is not very credible.  I'm not sure where the bug is in this
code, but the chance that it's in pstrdup is frankly zero.

According to the man page for strsep(), that function modifies the string
pointed to by its first argument.  I suspect you're failing to account
for that.  I'm also suspicious of the "// trim" code, which will misbehave
for a zero-length token.
